The MDN e-mail list continues, as detailed below

MOLECULAR DYNAMICS NEWS EMAIL LIST

All members of the chemical physics community are invited to join the (free) ``molecular-dynamics-news'' email list. The ``molecular dynamics'' in the title is to be interpreted as meaning ``dynamical processes in molecules'' rather than ``classical simulations of molecular motion''. The list can be used to distribute details of conferences, vacant academic and postdoctoral positions, changes of address and other news in the Molecular Dynamics field. It also serves as an archive of up-to-date email addresses for people in the field. The list was created by Jeremy Hutson in June 1993 and has now more than 1600 members.

Instead of being maintained manually, the list is operated by a system called ``mailbase''. People can join or leave the list simply by sending messages to the mailbase program, without the list owner needing to do anything. To join the email list, send a message to the Internet address mailbase@mailbase.ac.uk containing a line of the form:

join molecular-dynamics-news John F Kennedy

You do not need to tell the program your email address, as it picks it up from the message header. It does needs to be told your real name, so that it can maintain a useful list of email addresses.

When you join, you will receive some introductory information on how to circulate information to the molecular-dynamics-news list, and on the mailbase system itself.

If you would like a list of the current members, send a message containing the line

review molecular-dynamics-news

to the address mailbase@mailbase.ac.uk

Note that messages distributed via the e-mail list are not normally printed in the newsletter, unless the Editors receive an explicit request to do so.

Postdoctoral positions, Newly created International Astrophysics Network

We would like to introduce the newly created International Astrophysics Network.

The prime directives of this network are:
a. to combine the scientific potentials of highly motivated, flexible, and open minded research groups,
b. to establish goals/research lines investigating and unraveling the role of neutral - neutral reactions in the gas phase of the interstellar medium/planetary atmospheres and extraterrestrial ices,
c. exchange ideas what experiments/calculations are necessary and of paramount importance to the chemical processing of the ISM and planetary atmospheres,
d. perform experiments combined with theoretical treatment of these processes in extraterrestrial environments to setup a systematic database on reaction products and involved intermediates,
e. implement these data into chemical models of various interstellar environments and planetary atmospheres,
f. guide the search of hitherto unobserved molecules in the ISM and our solar system.
g. set up a data base to guide future space missions such as cometary matter return probes, Pluto express, Cassini/Huygens in an identification of hitherto unobserved molecules,
h. categorize hitherto observed interstellar/cometary molecules according to their formation route (solid state versus gas phase; ion-molecule reactions versus neutral - neutral reactions; distinct classes of neutral neutral reactions involving atoms, clusters, radicals),
i. encourage exchange of scientists between involved groups,
j. hold periodically informal workshops to advance the science/strategies in this field,
k. bring this research field into popular science and educational programs of schools.

The network consists of 6 sections:

Section 1 (laboratory experiments): Our group (group 1) performs neutral - neutral reactions relevant to the chemical processing of the interstellar medium and planetary atmospheres. These experiments provide data on the chemical reaction dynamics, energy dependent triply differential cross sections, involved intermediates, and reaction products.

In addition, our solid state machine is involved in neutral atom and low energy (< 5 keV) ion bombardments of extraterrestrial ice analogues to investigate the formation of molecules in extraterrestrial ices and on icy surfaces on interstellar grains. C.S. Lee's group at National Central University, Taiwan (group 2) performs ion bombardments of icy systems at higher energies between 5 and 20 keV. The third group ( L. d'Hendecourt et al.) is involved in ultraviolet photon irradiation of extraterrestrial ice analogues. These three groups will setup a systematic data base on the reaction products and involved intermediates and thus provide all the experimental data. Section 2 (electronic structure calculations): Electronic structure calculations investigate theoretically gas phase and solid state neutral - neutral reactions. These calculations will give information on the involved potential energy surfaces, reaction products, involved intermediates, and rotational constants together with vibrational frequencies of reaction products. These calculations are of fundamental importance in multi-atom systems as studies in groups 1 - 3 . Currently, the following groups are involved in this section: Y. Osamura (reactions of CN radicals with unsaturated hydrocarbons); M. Head-Gordon et al. (reactions of C atoms with small molecules of Ł 4 atoms), A. Mebel et al. (reactions of C atoms with intermediate sized molecules of 5 - 10 atoms), H.F. Schaefer/ P.v.R. Schleyer et al. (reactions of C atoms with large molecules > 10 atoms; reactions of C₂D/C₂H radicals; reactions of C₂/C₃ clusters with small molecules < 4 atoms; reactions of C₆H₅ radicals with unsaturated hydrocarbons).

Section 3 (RRKM studies): The results of sections 1 and 2 will be complemented and extended by (variational) RRKM calculations. This approach will give unprecedented information on absolute rate constants, theoretical reaction products and branching ratios if more than one product is formed. These investigations are performed by J. Peeters et al (Leuven, Belgium) et al (C/C₆H₆ system, CN/C₂D reactions with unsaturated hydrocarbons, C₆H₅ reactions, B reactions).

Section 4 (modeling): Results of sections 1 - 3 (absolute rate constants, reaction products, branching ratios) will be implemented by T. Millar (UMIST, UK) into models of molecular clouds, hot cores, and outflows of AGB stars. These models can predict theformation and abundance of observed/hitherto unobserved molecules in these environments.

Section 5 (observation): Based on sections 1-4, astronomers will search for hitherto unobserved, but postulated reaction products of neutral - neutral reactions in extraterrestrial environments. The key players in these observations are B. Turner (NRAO, USA), Dr. Y.N. Chih (IAA, Taiwan), T. Lee (IAA, Taiwan), C. Lemme (NCU, Taiwan), Y.J. Kuan (NCNU, Taiwan), and Y. Yung (Caltech, USA).

Section 6 (laboratory microwave spectra): Based on sections 1-3, McCarthy et al will record microwave spectra of hitherto unobserved astronomical molecules in the laboratory. These data will provide the rest frequencies necessary for the astronomical search.

Two post-doctoral positions, University of California, Santa Barbara

Two post-doctoral positions are available immediately in the laboratory of Professor Alec Wodtke at the University of California Santa Barbara. Chemical Interactions of vibrationally excited molecules with metal surfaces.

We are using stimulated emission pumping and overtone pumping to prepare single quantum states of highly vibrationally excited molecules. The excited molecules are carried in a molecular beam through a UHV chamber to a well-characterized surface and we observe scattering and surface sticking. So far, we have concentrated on interactions with clean metal surfaces. In these studies we have found strong evidence for vibration induced electron transfer and we intend to pursue this interesting result further. The project has already resulted in two papers in Science with another in the pipeline. One example of future work is to investigate the vibrational energy transfer to Shottky barrier diodes. Such experiments could directly reveal direct evidence of the electron transfer reaction, taking place at the surface and potentially lead to new laser-based molecular sensors. Another example of future work is the study of state-specific vibration induced surface reactions.

The project is an ongoing collaboration between Alec Wodtke and Daniel Auerbach. It is very well funded with an excellent array of equipment dedicated to the project: presently, three injection seeded Yag-pumped dye laser systems with non-linear optics and a molecular beam surface scattering apparatus. The experiment is quite demanding technically. We seek a person who likes high-tech experimental physical chemistry, has experience with laser spectroscopy and high vacuum equipment. The successful candidate must be independent and self-motivated. We believe this is an excellent opportunity for an ambitious individual to advance his or her career in basic research.

Interested individuals should send an electronic resume including at least two references to: Alec M. Wodtke, Wodtke@chem.ucsb.edu AND Daniel J. Auerbach, Dja@almaden.ibm.com .

Rapid Evaporative Cooling Mass Spectrometry of DNA We are finishing the construction of a custom time-of-flight mass spectrometer as part of an NIH funded study to develop new methods of high-speed gene sequencing. The approach exploits recent observations that molecules ionized from within van der Waals clusters can release large amounts of excess energy by rapid evaporation of weakly bound atoms and molecules. This is found to suppress fragmentation rates in the substrate by more than four orders of magnitude. Successful demonstration of suppressed fragmentation in mass spectrometry of DNA has many important implications. High-speed gene sequencing is one of them. The project is a collaboration between Alec M. Wodtke (physical chemistry and instrumentation) and Norbert O. Reich (an expert on DNA enzymology). It is still at an early stage and thus represents a great opportunity for someone to get in on the ground floor. Experience with any or all of the following: high vacuum methods, instrument design, mass spectrometry, laser desorption, photoionization and electron capture would all be seen favorably; however, we seek an individual who is interested in learning new methods. He or she should have a strong background in experimental physical chemistry but be intellectually flexible enough to learn and carry out experiments in biochemistry and even molecular biology, e.g. polymerase chain reaction, recombinant DNA methods. The successful candidate must be independent and self-motivated.

We believe that this position is an excellent opportunity for someone presently working in an area of experimental physical chemistry to branch out into modern biotechnology.

Interested individuals should send an electronic resume including at least two references to: Alec M. Wodtke, Wodtke@chem.ucsb.edu AND Norbert O. Reich, reich@chem.ucsb.edu .

Two Postdoctoral Research Assistants, University of Durham

Two Postdoctoral Research Assistants, in Theoretical Chemistry and Molecular Physics, to work with Prof. Jeremy M. Hutson University of Durham, England

Applications are invited for two postdoctoral Senior Research Assistantships to work with Prof. Jeremy Hutson on theoretical chemistry and molecular physics. The appointments will be for 1 year in the first instance, starting as soon as convenient (preferably before 1 August 2000). Application may be made either online (via http://www.dur.ac.uk/Personnel/vacancies/lra.htm or on forms available from the Personnel Office, University of Durham, Old Shire Hall, Old Elvet, Durham, DH1 3HP ( email: Acad.Recruit@durham.ac.uk ). Please quote reference A116C. Completed forms, accompanied by a full curriculum vitae and the names of two academic referees, must be received by the Personnel Office by 27 April 2000.

When applying, please make it clear whether you are interested in both of the positions available or just one of them.

The Research Projects and Job Descriptions

Position 1: Long-range forces and cold molecules

It is now possible to trap gas-phase molecules at very low temperatures (below 1 K), and molecule formation in a Bose-Einstein condensate at 10^-7 K has just been reported for the first time (Wynar et al., Science 287, 1016: February 2000). We have been working on an EPSRC-funded project on long-range interactions between atoms and molecules; the spectra of near-dissociation states of ionic complexes such as He-Ar⁺, Ne-Ne⁺. HeN⁺ and He-H₂⁺, which have been measured by Carrington and coworkers (Southampton), have been used to learn about atomic and molecular interactions at very long range and the dynamics of near-dissociation states (see J. Chem. Phys. 102, 2379 (1995), J. Chem. Phys. 105, 8602 (1996), Chem. Phys. Lett. 260, 395 (1996) and J. Chem. Phys. 110, 3418 (1999) for more details).

The Research Assistant will work Prof. Jeremy Hutson and Dr. Pavel Soldan to understand the role of long-range forces in cold collisions and the properties of cold and ultracold molecules. Interesting questions involve the role of 2-body and 3-body collisions and the behaviour of inelastic and reactive scattering cross sections at very low energies (from 1 K to 10^-8 K).

Position 2: Fitting potential energy surfaces

We have recently developed a procedure for "morphing" ab initio potential energy surfaces to fit experimental data. The original potentials need not be of ßpectroscopic" quality, but are "bent and stretched" to bring them into agreement with experiment. The morphing procedure offers the prospect of obtaining potentials of ßpectroscopic" quality for much larger systems than previously. [See M. Meuwly and J. M. Hutson, "Morphing ab initio potentials: a systematic study of Ne-HF", J. Chem. Phys. 110, 8338-8347 (1999).]

The current project is to extend the morphing procedure in a variety of directions:

Systems involving flexible and vibrating molecules
Systems involving non-linear molecules
Systems involving open-shell atoms and molecules

There may be be opportunities for the successful applicants to participate in making research grant proposals and to undertake some teaching duties.

Further information on the research group and the University of Durham is available at http://www.dur.ac.uk/~dch0www/Staff/jmh

For both positions, the successful applicant will require either a Ph. D. or postdoctoral research experience in theoretical chemistry or chemical physics.

The salary will be on the standard RA 1A scale for research staff in UK Universities. The scale runs from 16,286 to 24,479 pounds per annum (under review) according to age and experience, but the funding available is such that these appointments will have to be made near the lower end of the scale.

Unless otherwise requested before appointment, the Research Assistant will be a member of the Universities Superannuation Scheme, under which the employee's contribution is 6.35% of salary and the University currently contributes an amount equivalent to 12.5%.

Theoretical Chemistry at the University of Durham

Theoretical Chemistry at the University of Durham has been expanding in recent years. There are now four theoretical research groups, which are housed in refurbished space in the newly created Wolfson Centre for Molecular Interactions. The research group leaders are:

Jeremy Hutson: Theoretical chemical physics, especially spectroscopy and dynamics of Van der Waals complexes and clusters; intermolecular forces; molecular collisions; spectroscopic lineshapes and the greenhouse effect.

Mark Wilson: Atomistic simulations of molecular materials, especially liquid crystals.

David Tozer: Fundamental aspects of density-functional theory, especially the development of new functionals that behave properly at long range.

Stuart Althorpe: Chemical reaction dynamics, especially wavepacket methods and their extension to larger reacting systems.

Computers: We have an 8-processor Silicon Graphics Origin 2000 system with 4 GB of shared memory. An additional large multiprocessor machine is currently being purchased.

In addition, the group uses a variety of workstations for program development, and has access to the CRAY T3E supercomputer at Manchester. There is also access to Departmental and central University facilities. All the machines are of course fully networked, with a well-integrated local Ethernet and access to remote sites via SuperJanet.

The Durham/Newcastle Theoretical Atomic & Molecular Physics Group

The Universities of Durham and Newcastle have a very active research community in atomic and molecular physics. The group is interdisciplinary, with members in the Physics and Chemistry Departments at Durham and Newcastle.

The research group leaders outside the Durham Chemistry Department are:

Alan Dickinson (Newcastle Physics): Semiclassical methods for molecular collisions; non-adiabatic processes in atomic collisions; transport and relaxation properties of ions and molecules in gases; collision kernels.

David Flower (Durham Physics): Charge-transfer collisions between atoms; molecular collisions of astrophysical importance.

Ian Cooper (Newcastle Chemistry): Calculation of potential energy surfaces for charge transfer and photoionization applications; use of algebraic methods in molecular spectroscopy, structure and dynamics.

Robert Potvliege (Durham Physics): Multiphoton processes in atoms: theoretical study of multiphoton ionization and of harmonic generation in intense laser fields, laser-assisted scattering processes.

Charles Adams (Durham Physics): Experimental and theoretical studies of laser cooling and atom optics.

Brian Bransden (Durham Physics): Charge-transfer collisions between atoms; positron scattering.

POSTDOCTORAL POSITION, NORTHWESTERN UNIVERSITY

I expect a postdoctoral position to be available in my group as part of the recently established Institute for Environmental Catalysis at Northwestern. The position will focus on studies of a number of reaction processes of critical importance in "real world" environmental problems. One focus is the role of alkyl radicals in lean NOx chemistry in a zeolite environment. This ties in with other work within the Institute that is directed toward the development of novel catalytic materials that can operate under lean NOx conditions. Another focus is a detailed understanding of the mechanism(s) of photoinduced reactions of halogenated hydrocarbons on titania (TiO₂) surfaces. This is linked to other studies within the Institute that are directed toward more efficient waste water purification using photo and biocatalytic techniques. Time resolved spectroscopy will be a primary experimental probe in our studies.

This position offers a unique environment for scientific research. A goal of research within the Institute is to use fundamental, molecular level, scientific investigations to address problems in catalysis that bear on "real world" environmental issues. Researchers within the Institute work in a collaborative environment. They come from a number of departments and have a broad range of backgrounds and interests. This environment provides exposure to a variety of perspectives and techniques.

Experience with some aspect(s) of time resolved laser based techniques is desirable. Prior experience with zeolites and/or titania is not a prerequisite. Availability around mid-summer is highly desirable. However, I would consider waiting for an appropriate candidate. An application should include a CV, with publication list, and three letters of recommendation sent to:

Professor Eric Weitz,
Department of Chemistry, Northwestern University
2145 Sheridan Road, Evanston, IL 60208-3113
Phone: 847-491-5583, e-mail : WEITZ@NWU.EDU .

POSTDOCTORAL POSITION AT COMPLUTENSE UNIVERSITY, MADRID

April, 2000

Applications are invited for a postdoctoral fellowship in Gas Phase Reaction Dynamics under the supervision of Professor F. Javier Aoiz and funded by the European Union RTN (Research Training Network) programme, as part of the RTN Network on "Reaction Dynamics: experimental and theoretical studies on the dynamics of reactions of atoms and radicals of fundamental and practical importance". This programme involves seven laboratories: University of Perugia (Italy), University of Oxford (UK), University of Nijmegen (The Netherlands), University of Bielefeld (Germany), University Complutense Madrid (Spain), University of Stuttgart (Germany), University of Muenchen (Germany).

The projects to be developed in our laboratory are concerned with experimental studies of photon initiated elementary chemical reactions in a molecular jet/beam and of photodissociation of molecules containing sulfur and halogens by using resonance enhanced multiphoton ionization (REMPI) and time-of-flight mass spectrometry (TOFMS). In addition, theoretical work based on quasi-classical trajectory and quantum mechanical reactive scattering calculations of the dynamics of the reactions studied experimentally will be performed.

The position (for up to 3 years duration) for young post-doctoral researchers with experimental and/or theoretical skills in the field of Reaction Dynamics is available from April 2000 although the exact commencement date is negotiable. Given the strong links between the different groups in the RTN, the post-doc is expected to spend up to one month each year in another laboratory of the RTN "Reaction Dynamics". Salary is about 3000 euro/month (before taxes).

Postdoc Announcement, Northwestern University

We are looking for a postdoc! The process of dip-pen nanolithography, that was developed by Chad Mirkin at Northwestern, involves preparation of nanostructured patterns on metal surfaces, by deposition from the aqueous meniscus formed between an AFM tip and the metal surface. While this is the macroscopic characterization, there are some wonderful microscopic questions involved: how does the process work? What is the role of surface energy? Does it depend on the speed of deposition or the concentration? What are the forces involved? What are the characteristics of the line, and how does that determine the fractal dimensionality and conductance?

The two of us will be working on this topic together, and we will be delighted to support a postdoc whose interests are in molecular dynamics simulations. If you have somebody with those interests, please let us know. The position will pay a competitive salary, and we think that working in this group on this problem will be challenging and enjoyable.

You can correspond with either of us. Thanks for your help on this and very best wishes.

The Research Project and Job Description

Rovibrational Quantum States of 4-atom systems: Recent advances in experimental spectroscopy and the requirements of atmospheric chemistry, astrophysics and combustion chemistry have led to a need for the accurate prediction and understanding of the high lying (wide-amplitude) vibration-rotation states of small molecules. Great progress has recently been made in the variational calculation of the vibration-rotation energy levels, wavefunctions and spectroscopic transition intensities of triatomic molecules and such calculations are now becoming routine (for closed-shell systems). However high precision rotation-vibration calculations on tetraatomic species represent an important frontier in the quantum molecular dynamics field. Systems involving multiple minima and/or high rotational excitation are particularly challenging and represent the major targets of this project.

The Research Fellow will work with Dr. Mark Law to produce a suite of computer codes usable by a wide research community and capable of accurate calculations of the rovibrational bound state energies and wavefunctions (and hence transition intensities) of all closed-shell tetraatomic molecules and complexes.

The computer programs will be developed using Sun and Dec-Alpha workstations in Aberdeen, with access to the Cray T3E parallel supercomputer facility at Manchester (CSAR) for computationally intensive work. There is also access to Departmental and central University facilities. All the machines are of course fully networked, with a well-integrated local Ethernet and access to remote sites via SuperJanet.

There may be opportunities for the successful applicant to participate in making research grant proposals and to undertake some teaching duties.

Although based in Aberdeen, the Research Fellow will be expected to collaborate with other groups in the UK, to ensure that the programs developed are useful to the CCP6 community as a whole (see below). In particular the project will involve regular and close consultation and interaction with Prof. Jeremy M. Hutson (Durham) and Prof. Jonathan Tennyson (University College London).

In addition to this research work, the Research Fellow will take a role in coordinating CCP6 activities and helping to organise CCP6 Working Group meetings and conferences.

Interests of Research Groups Associated with the Project

Dr. Mark Law (Aberdeen): Theoretical interpretation of molecular spectra; vibration-rotation energy levels of small molecules; intramolecular vibrational energy redistribution; determination of molecular potential energy surfaces; computational chemistry using parallel computing methods; development of the methodology of fitting physical models to data.

Further information on Mark Law's research group and the University of Aberdeen is available at http://www.abdn.ac.uk/~che194/

Prof. Jeremy Hutson (Durham): Theoretical chemical physics, especially: spectroscopy and dynamics of Van der Waals complexes and clusters; intermolecular forces; molecular collisions; spectroscopic lineshapes and the greenhouse effect.

POSTDOCTORAL POSITION, C. S. PARMENTER RESEARCH GROUP, INDIANA UNIVERSITY

A postdoc appointment for a recent PhD is available with the experimental chemical physics group of C. S. Parmenter. The research concerns vibrational and rotational dynamics in gas phase molecules with six to thirty modes.

Two studies focusing on collisional energy transfer will receive much attention in the next few years. One is designed to reveal the steric effects that underlie these collisional interactions. While predicted by theory to be large, steric influences on inelastic collisions with polyatomics have never before been experimentally accessible. We are using crossed molecular beams to give state-to-state resolution of single collision rotational and rovibrational energy transfer channels in planar or near-planar symmetric top molecules. A laser pumps an initial vibrational level in an electronically excited state with selected angular momentum around the top axis. To achieve control over the collision geometry, molecules are aligned using the laser polarization as guided by recent theory. (JCP 107, 7138 (1997), JPC-A 101, 9594 (1997)) The alignment establishes bias toward edge-on or broadside encounters. Dispersed fluorescence yields relative cross sections for the competition among dozens of individual rotational and rovibrational channels that will produce a comprehensive picture of steric influences.

The other is directed at the collisional activation/deactivation of large molecules with the high vibrational energy needed for unimolecular reaction. Despite years of study, one basic measurement remains elusive, namely the absolute total cross section for energy transfer into the neighboring vibrational field for these highly excited molecules. We are using a new twist on our oxygen fluorescence quenching method (chemical timing) that has long been associated with collision-free vibrational dynamics to produce these measurements. The method is adapted to a collisional environment that produces absolute cross sections for vibrationally excited molecules with state densities of thousands of levels per wave number.

Applicants should submit a CV and arrange to have letters of recommendation sent on their behalf.

POST-DOCTORAL POSITION AT EPA

Chemical Physicist/Physical Chemist with experience in the use of laser-based spectroscopic methods for measurement of gaseous species. The ideal candidate will have hands-on experience with resonance enhanced multiphoton ionization (REMPI) or other laser spectroscopy of molecules. The candidate will work in an applied program that couples REMPI with time-of-flight mass spectrometry (TOFMS). The candidate will work with the leading international laser spectroscopy groups developing the REMPI analytical method and designing and building an instrument for use at EPA. Candidate will apply REMPI instrument for detection of trace halogenated air toxics as part of a comprehensive program at the EPA's combustion research facility in Research Triangle Park, NC, investigating the formation mechanisms of these pollutants.

Background

The U.S. EPA's Office of Research and Development, National Risk Management Research Laboratory (Research Triangle Park, NC) conducts research on formation mechanisms, quantification methods, and prevention of hazardous air pollutants, particularly halogenated organics such as chlorinated dibenzodioxins/dibenzofurans, biphenyls, and napthalenes. Recently, NRMRL has been awarded a grant to study the application of REMPI/TOFMS techniques toward development of a real time "dioxin" monitor. This grant program, combined with a DOE-funded program to develop the instrumental science behind REMPI/TOFMS, constitutes a large federally-funded effort whose goal is to develop this method of hazardous air pollutant detection for source characterization, understanding of pollutant formation mechanisms, and pollution prevention. As part of this program, a REMPI/TOFMS system will be built for use at EPA's combustion research faciltiy. The post-doctoral laser spectroscopist is necessary to operate the REMPI/TOFMS system and develop its application for trace halogenated species detection. Candidate will work with a team of researchers investigating hazardous air pollutant formation on in-house facilities including waste combustors, industrial boilers, solid fuel combustors, rotary kilns, and laboratory reactors.

Particulars

The optimal timing for arrrival of this post-doctoral candidate is January-March, 2000. This timing will allow the candidate to work with the REMPI developer as they put together the instrument, allowing the candidate to better understand how the REMPI/TOFMS system works. Salary is US48,000 per year. This position is open to foreign nationals as well as U.S. citizens.

'SiO Maser Modelling - Assessment of Mass Loss and Hydrogen Concentrations in Late Type Stars'

Applications are invited for a post-doctoral position to work on a challenging project which seeks to investigate the rate of mass-loss from late type stars.

The candidate should have expertise in one or more of the following areas: 1) quantum- mechanical scattering theory; 2) ab-initio molecular electronic structure theory; 3) radiation transport and hydrodynamics. The project will use advanced techniques and computer codes from all these disciplines at different stages.

The objectives of the project will be to model the SiO maser radiation from the region of late type stars and from this modelling to ascertain the state and quantity of the hydrogen gas present in the region where mass-loss is initiated. This in turn will permit an estimation of the rate of mass loss from the stars involved.

In order to model the maser radiation an improved knowledge the vibrationally-rotationally inelastic collision cross sections of SiO with the most abundant available collision partners is needed. The project is already well under way and we have nearly finished the calculation of the necessary interaction potentials. The next stage of the project will be the computation of inelastic collision cross sections using these potentials followed by the use of the computed cross sections in maser modelling calculations.

The successful candidate will work with Prof. Gabriel Balint-Kurti (School of Chemistry), Dr. Malcolm Gray (Department of Physics and Astronomy, University of Wales, Cardiff) and Prof. David Field (Institute of Physics and Astronomy, Aarhus, Denmark). Applications should be made to Prof. G.G. Balint-Kurti ( School of Chemistry, University of Bristol, Bristol BS8 1TS, UK) and should supply the names of two referees.
