L(2,3)M(4,5)M(4,5) X-RAY-EXCITED AUGER-ELECTRON SPECTRA OF AG

We have investigated the L(2,3)M(4,5)M(4,5) Auger spectra of Ag excited with bremsstrahlung. The main experimental spectra are in good agreement with atomic-multiplet-structure calculations in which the initial state is treated in jj coupling and the Anal state in the intermediate coupling scheme. Anomalous loss structures appear at lower energies than those of the main spectra. These losses appear to be atomic in origin and are not manifest in the corresponding spectra of In, Sn, and Sb. We demonstrate that these losses are consistent with a model of d-band spectator vacancy shake-up satellites. Coster-Kronig processes present in Cu appear to be absent here.
