Self-consistent analysis of iVV-Auger fine structure

Abstract

It is shown from the principles of the two-electron process in Auger-type transitions involving core-band-band excitations that a self-consistent set of guidelines can be developed for use in line-shape analysis. Three conditions derive from energy transformation considerations and two from the properties of the Auger convolution integral. It has been found that the use of such conditions is of considerable aid in the analysis of Auger fine structure for information such as chemical bond characteristics. It is recommended that these necessary constraints on the interpretation of Auger fine structure be considered to establish some credibility for fine structure analyses. Although complex structures may require a deconvolution analysis, it is evident that much can be learned about simple spectra from the other guidelines given herein.
