Chemical shifts of .Auger electron lines and electron binding energies in free molecules. Silicon compounds.

The complete KLL and KLM Auger electron spectra of argon have been recorded at high resolution. The satellite lines in the KLL spectrum have been investigated and relativistic multiconfigurational Dirac-Fock calculations have been made to suggest assignments for these structures. Investigations of the neon KLL spectrum are employed to interpret part of the shake-off satellites.

High resolution KLL Auger electron spectra of H2S, SO2 and SF6 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.
