Abstract

The non-dipole contribution to spin polarization of photoelectrons from Xe, Cs and Ba 3d5/2 and 3d3/2 levels is calculated. The calculation is carried out within the framework of a modified version of the spin-polarized random phase approximation with exchange. The effects of relaxation of excited electrons due to the 3d-vacancy creation are also accounted for. It is demonstrated that the parameters that characterize the photoelectron angular distribution as functions of the incoming photon energy, although being predictably small, acquire additional peculiarities when the interaction between electrons that belong to the 3d5/2 and 3d3/2 components of the spin–orbit doublet is taken into account.
