Lifetime and Auger decay of strongly correlated 4p hole states of xenon

The xenon 4p photoelectron spectrum and the subsequent 4p −1→(5s,5p) −2 Auger and 4p −1→4d −1(5s,5p) −1 Coster–Kronig spectra have been studied with the aid of a high-resolution experiment and multiconfigurational Dirac–Fock calculations. Strong electron correlation is known to affect drastically th...

Description
Summary:The xenon 4p photoelectron spectrum and the subsequent 4p −1→(5s,5p) −2 Auger and 4p −1→4d −1(5s,5p) −1 Coster–Kronig spectra have been studied with the aid of a high-resolution experiment and multiconfigurational Dirac–Fock calculations. Strong electron correlation is known to affect drastically the Xe 4p photoelectron spectrum: the 4p 1/2 component disappears completely, and the intensity of the 4p 3/2 line is redistributed into several close-lying peaks. We have calculated the lifetime widths of the photoelectron peaks, simulated the observed photoelectron and Auger spectra and compared theoretical results with experiment.
