Photoionization of Ti3+: β parameter and Momentum Transfer

Abstract

Synopsis Key issue is the presentation of the unpublished 4 angular factors arising from the 4 paths when momentum transfer induces asymmetry β in photoionization calculations. They require functional expansions such as the frozen cores approach which are not bedevilled by the prior-post dilemma. It is essential to consider all magnetic 2-body terms in the Breit-Pauli hamiltonian that contribute to finestructure.
