Abstract
Results of an investigation of dynamics of excited state production in collisions of inert gas projectiles on Na, Mg, Al and Si surfaces are presented. Angle resolved measurements of charge fractions and electron spectra are reported. The efficiency of excited autoionising state production as a function of energy is determined. These results are compared to known gas phase collision results. A similarity in the general trends of excited state production, suggests that both in gas phase and in ion‐surface collisions similar primary excitation mechanisms are operative. However surface specific electron capture, loss, deexcitation and core rearrangement processes lead to a strong modification in final state distributions and a dominant selective production of the lower lying excited states occurs. Modifications induced by oxygen adsorption are discussed.
