X-ray and Auger de-excitation processes in resonantly-excited and core-ionized molecules

Abstract

Some recent developments in the understanding of molecular Auger and X-ray spectra are reviewed. Factors leading to complex molecular Auger spectra are discussed. The importance of correlation satellites in some spectra, such as for the SiF 4 molecule, are reported. The prediction of inner-shell photoelectron linewidths and the discrepancies with experiment for silicon-containing molecules are reported. The strong dependence of resonant X-ray emission spectra on photon excitation energy is discussed in the context of the CO 2 and N 2O molecules.
