Numerical solutions of the time-dependent Schroedinger equsation for the one and two electron ions H₃²⁺, H₃+, H₄³⁺, H₄²⁺, H₅⁴⁺, H₅³⁺, have been obtained in short(t < 50 fs)intense(I > 10**14W/cm² ) laser pulses in order to study the role of electron-electron interactions on high order harmonic generation,into the X-Ray region. One electron systems are found to generate harmonics with maximum energy IP + 6 Up whereas two electron systems give maximum photon energies IP + 12 Up, where IP is the ionization potential and Up the ponderomotive energy. These high photon energies are produced by electron-electron and nuclear collisions.

Molecular beam experiments on collisions between oxygen molecules were performed at low energy and high angular resolution, with the control of the relative orientation of the colliding molecules. Dependence on relative orientations for the ground singlet state surface and for the excited triplet and quintet states is obtained. These results indicate that most of the bonding in the dimer comes from electrostatic (van der Waals) forces but chemical (spin-spin) contributions in this open-shell--open-shell system are not negligible.

Department of Chemistry, Darmstadt University of Technology, May 27 - 29, 1999

Scope of the Symposium: Large and complex systems provide some of the most challenging experimental and theoretical problems in modern chemistry. By complex systems, it is meant that the systems as well as the models used should reflect chemical conditions in a realistic way. This requires the proper and simultaneous treatment of different species and phases. The purpose of this symposium is to survey recent research in the development of new model scenarios, new theoretical approaches and simulation techniques of complex systems and processes as well as subtle experimental techniques in order to study these kinds of systems.

It is the aim of this meeting to discuss various ways to overcome the limitations of individual methods by combining different approaches and to demonstrate in this way the power of new concepts and technologies.

The invited speakers are selected from a wide variety of fields ranging from philosophy to preparative chemistry. Therefore, the meeting is expected to be of interest to both experimentalists and theorists from all branches of science, as well as mathematicians and computer scientists.

Perugia, Italy, 25-27 June, 1999

The meeting, which will be sponsored by the D9 COST Action in Chemistry, will hopefully be attended by most of the world experts in the field, and will be run in the same spirit and with the same objectives as the four previous workshops on reactive scattering (Cambridge UK, 1990, organised by David Clary, Cambridge USA, 1994, organised by Yan Sun and Michael Baer, Nottingham UK, 1995, organised by David Clary and David Manolopoulos, and Telluride, Colorado, 1997, organised by Joel Bowman). The emphasis of the workshop will be on the latest theoretical developments and the most impressive recent calculations. The most ingenious new approximations in reactive scattering will also be discussed. Interesting new directions for the application of reactive scattering theories will also be discussed, with special attention towards systems of increasing complexity, according to the aims of the D9 COST Action.
