Molecular Auger Electron Spectra of Second Row Elements. Sulfur Compounds

Abstract

High resolution KLL Auger electron spectra of H 2 S, SO 2 and SF 6 are presented and analyzed. The experimental equipment, using a recently designed electron retardation system, is described. For the analysis of the spectra, ab initio computations have been performed including configuration interaction. The discussion is mainly focussed on the satellite structure. The major satellites are due to shake-off in the valence shell accompanying the K-ionization and are found to be chemically dependent. Extra lines are also observed, which are assigned to autoionization processes.
