Title: Angular Distributions of s -Subshell Electrons in Open-Shell Atoms: 3s Photoionization of Atomic Chlorine

Abstract

A determination of the angular distribution parameter {beta} of the atomic chlorine 3s photoelectrons over the photon-energy range from 29 to 70 eV has been carried out using electron spectrometry in conjunction with synchrotron radiation. Our results confirm the basic theoretical predictions that {beta} , for s -subshell photoionization in open-shell atoms, is in general term and photon-energy dependent, in contrast to closed-shell atoms where {beta} is always 2 nonrelativistically. However, our measurements of {beta} for the Cl{sup +} 3s({sup 1,3}P) channels demonstrate that significant details are not handled well by simple Hartree-Fock theory.
