Relevance of the Core Hole Alignment to Auger–Photoelectron Pair Angular Distributions in Solids

Coincidence spectroscopy: Past, present and perspectives

“…More recent studies on an ion-bombardment amorphized Si(100) surface have lead to a quantitative determination of the average emission depth of both the Auger and the photoelectrons [174]. Further experimental work of Stefani et al [175] shows that by using the angular resolved Auger electron, photoelectron coincidence spectroscopy approach one can investigate the core ionization mechanism in solids with l and m l quantum numbers selectivity, i.e. one can uniquely correlate the dicationic final states magnetic substates to the monocationic magnetic sublevels.…”
