Abstract

The desorption of ions induced by electronic transitions involving core levels has been studied intensively during the last decade (1). It is well recognized that Auger decay is an important mechanism to produce active states for ion desorption in ionic as well as covalent compounds (2). However, it is also clear that the ion desorption yield induced by core excitation is not proportional to the total core hole production rate (3). Therefore a detailed analysis of initial excited states, their decay channels and the corresponding final states is needed for further progress towards a comprehensive knowledge of the basic mechanisms and possible applications of photon and electron stimulated ion desorption (PSD and ESD). The present study is intended to provide an example of such an analysis.
