Theoretical study of the photoelectron intensities and angular distributions

Abstract

The intensity and the angular distribution in photoelectron spectroscopy are calculated for some simple molecules by taking the hydrogen-like continuum function for the ejected electron. Relative intensities calculated for neon, methane, water, argon and hydrogen sulphide are in good agreement with the experimental results of ESCA. The forced orthogonality of the continuum function to the bound orbitals has a significant effect on the asymmetry parameter β. Calculations assuming the plane wave for the ejected electron are also performed and compared with those made by taking the hydrogen-like continuum function.
