Abstract
The separation energy spectra following the removal of the 5s-valence electron in xenon either by a photon ({gamma},e) reaction or a fast electron ((e,2e) reaction) is calculated. Relative line intensities in the (e,2e) spectrum are equal to the corresponding spectroscopic factors being determined as the single-hole Green`s function pole strength. The Green`s function accounts for virtual two-hole-one-electron excitations of 5p{sup 4}nl,l=d,s type. Spin-orbit interaction is taken into account by constructing 5p{sup 4}nl J{sup {pi}}=1/2{sup +} eigenvectors from different 5p{sup 4}(L{sub 1}S{sub 1})nl LS Hartree Fock states of which the only 5p{sup 4}({sup 1}D)nd{sup 2}S{sub 1/2} states are allowed to interact with one-hole 5s{sup 1}5p{sup 6} {sup 2}S{sub 1/2} state. Relative line intensities in the ({gamma},e) spectrum are influenced by the atomic ground state correlations, which change most significantly the intensity of the main line and the continuous spectrum. Results of the calculation are in a good agreement with both type of experiments for strong {sup 2}S-symmetry satellites. The structure of satellites of other types of symmetry is reproduced qualitatively. 15 refs., 3 tabs.
