Title: Electron spectroscopy studies of atomic inner-shells

Abstract

The authors have used electron spectroscopy combined with tunable synchrotron radiation in the 2-5 keV energy range for several studies of atomic inner-shell excitation and vacancy decay processes. These studies have focused on Ar 1s photoelectron spectra and Ar KLL and LMM Auger electron spectra. The electron spectra provide an overview of the states involved in nonradiative decay following excitation of a 1s electron to a bound or continuum state. Detailed studies have also been made of doubly-excited states in the excitation and photoelectron spectra and of Auger resonant Raman scattering. In addition, several novel results have been obtained by recording electron spectra in coincidence with fluorescent x-rays to select subsets of the decay pathways. Distortion of the Ar Is photoelectron spectrum due to post-collision interaction with K-Auger electrons is eliminated in the coincidence spectra. The complexity of LMM vacancy-cascade electron spectra is greatly reduced when measured in coincidence with K-fluorescence, allowing state-specific assignments.
