Title: Linear polarization of the 2p{sup 5}3s{yields}2p{sup 6} lines following the inner-shell photoionization of sodiumlike ions

Abstract

The inner-shell photoionization of highly charged, many-electron ions and their subsequent radiative decay are studied theoretically within the multiconfiguration Dirac-Fock approach. Special attention is paid to the linear polarization of the characteristic x-ray radiation. Detailed calculations have been carried out, in particular for the 2p{sup 5}3s{yields}2p{sup 6} radiative transitions following ionization of the 2p electron of the sodiumlike iron Fe{sup 15+} and uranium U{sup 81+} ions. For these elements, the inner-shell photoionization was found to induce the (relatively) low linear polarization of the subsequently emitted photons which is strongly affected, moreover, by the higher-order (nondipole) effects in the electron-photon interaction.
