Photoelectron Angular Distributions ofsElectrons in Open-Shell Atoms

Abstract
It is shown that the photoelectron angular distribution of s electrons in an open-shell atom, having outer configuration ns2npq, is not described by the asymmetry parameter β=2, as predicted by more approximate theories, but has dramatic variations with energy even within LS coupling. Calculations for the 3s subshell in Cl are presented as an example.
