Professor Philip G. Burke, CBE, FRS formally retired on 30 September 1998. To recognise this occasion some of his colleagues, friends, and former students decided to hold a conference in his honour and to present this volume as a dedication to his enormous contribution to the theoretical atomic physics community. The conference and this volume of the invited talks reflect very closely those areas with which he has mostly been asso- ated and his influence internationally on the development of atomic physics coupled with a parallel growth in supercomputing. Phil’s wide range of interests include electron-atom/molecule collisions, scattering of photons and electrons by molecules adsorbed on surfaces, collisions involving oriented and chiral molecules, and the development of non-perturbative methods for studying multiphoton processes. His devel- ment of the theory associated with such processes has enabled important advances to be made in our understanding of the associated physics, the interpretation of experimental data, has been invaluable in application to fusion processes, and the study of astrophysical plasmas (observed by both ground- and space-based telescopes). We therefore offer this volume as our token of affection and respect to Philip G. Burke, with the hope that it may also fill a gap in the literature in these important fields.

We are investigating the interactions of hyperthermal energy (few to several hundred eV) atomic ions with metal surfaces, focusing on ion-surface charge exchange processes. For Li+ scattering from alkali-covered Cu(001), we have measured branching ratios for Li+, Li- and ground- and excited-state Li deg in the scattered flux. These results are interpreted using a state-of-the art multi-channel charge transfer code developed by Brad Marston. Using this code, we have gained important insights into the dynamics of multi-channel charge transfer processes. We are extending these studies to higher-lying excited states of Li, excited state formation in Na scattering, and multi-channel charge transfer in 0 scattering. For Na+ scattering from clean Cu(001) we have observed trajectory-dependent charge transfer in which the charge transfer probability is dependent on the collisional history of the particle; evidence is found for modification of the neutralization due to defect formation that can occur in certain types of collisions with the surface. We plan to study trapping behavior for hyperthermal energy alkalis and oxygen incident on metal surfaces.

The aim of this volume is to underline common aspects of dynamical properties of surfaces and adsorbates which can sustain energy transfer and to assess the role and importance of specific energy and charge transfer mechanisms in constituting the properties of surface and adsorbate electronic, vibronic, photoabsorption and similar spectra, the dynamics of adsorption/desorption and trapping processes, surface scattering phenomena involving electrons, ions or neutral particles etc. In this regard, special attention has been paid to model descriptions and discussions of inelastic interactions, screening and charge transfer processes encountered in XPS, AES, EELS, NEXAFS and electron, atomic/molecular and ion beam scattering experiments.
