The following aspects of the title subject will be discussed making use of recent and partly unpublished results Evidence for mtrmslc photo-desorptlon from adsorbates on metals, Evidence for core ionization as primary process in ESD and PSD not only for insulators (Knotek and Felbelman), but also

for adsorbates on metals, and specifically adsorbates,

for covalent

Bearing of these results on the mechamsm of ESD and PSD primary and secondary processes, relative ~mportance of recapture, RMG (Redhead MenzeLGomer) versus KF (Knotek Felbelman) mechamsm, thezr compatlbd~ty and differentiation, Use of core lomzaUon m PSD for EXAFS studies
