Abstract

The 3p excitation cross section in the 3d transition metals shows a resonant maximum in photoabsorption and electron energy loss spectroscopy. The resonant 3p excitation is shown to decay into various decay channels with Auger decay and direct recombination being most prominent. Electron and photon stimulated ion desorption from the 3d transition metal oxide surfaces is initiated by Auger induced 2 hole and 2 hole. 1 electron final states. In Cr(110) O2 the O+ yield differs significantly from the total secondary electron yield. This rules out electron stimulated ion desorption induced by secondary electrons. It is the first instance of a pronounced core hole state sensitivity observed in PSD. © 1985.
