L/sub 2,3/-M/sub 4,5/M/sub 4,5/ Auger-electron spectra of the metallic elements /sub 47/Ag to /sub 51/Sb: An analysis of the main and satellite structures

The L/sub 2,3/-M/sub 4,5/M/sub 4,5/ Auger-electron spectra of the metallic elements /sub 47/Ag to /sub 51/Sb have been measured. The spectra are analyzed within the framework of Hartree-Fock differential self-consistent-field (ΔSCF) calculations in which correlation and relativistic energy shifts have been included, using jX(hyj coupling for the initial state and intermediate coupling for the final state. It is found that structure on the low-energy side of the L3-M/sub 4,5/M/sub 4,5/ spectrum, previously interpreted as due to the L3M/sub 4,5/-M/sub 4,5/M/sub 4,/ 5M/sub 4,5/ multiple-hole excitations following the L1-L3M/sub 4,5/ Coster-Kronig decay process, is also present in the L2-M/sub 4,5/M/sub 4,5/ spectrum. Electron energy-loss spectroscopy data show that the structure in fact corresponds to plasmon satellites. The L3M/sub 4,5/-M/sub 4,5andand//sub M//sub >4/, 5M/sub 4,5/ satellites are revealed in /sub 47/Ag and /sub 48/Cd by an anomalous value of the intensity ratio of the L3-M/sub 4,5/M/sub 4,5/ and L2-M/sub 4,5/M/sub 4,5/ groups. The L/sub 2,3/ level widths of the elements /sub 47/Ag to /sub 51/Sb are determined from a simulation of the experimental spectra using our theoretical results
