Title: 5p photoemission from laser-excited cesium atoms

Abstract

Fine-structure resolved 5p photoemission spectra of Cs in the ground state and after laser excitation into the [Xe]6p {sup 2}P{sub 1/2} and 6p{sup 2}P{sub 3/2} states have been studied. The 5p{sup 5}6p final states have been reached by the 5p{sup 6}6s{yields}5p{sup 5}6p conjugate shakeup process from ground-state atoms as well as by direct photoemission from laser-excited atoms. The laser-excited spectra can be well described with calculations based on the jK-coupling model. Calculations based on a multiconfiguration Dirac-Fock approach have been performed to investigate the deviations created by intermediate coupling from the pure jK-coupling scheme.
