Angular distribution of 3p photoelectrons in Cr and Mn

Abstract

A peculiar energy dependence of the angular distribution of 3p photoelectrons in Cr and Mn atoms is discovered. Calculations are performed within the random-phase approximation with exchange generalised for atoms with half-filled shells using the spin-polarised Hartree-Fock approximation as the zero-order approximation. Variations discovered in the behaviour of the angular anisotropy parameter are due to intershell interactions of electrons.
