Manifestation of FISCI effects in the total and differential cross sections of the correlation satellites in the rare gases Kr and Xe

Photoionization cross sections, σ, and angular distribution asymmetry parameters, β, for the majority of levels manifested in the subvalence ns-shell photoelectron spectra of the Kr and Xe atoms are calculated. For many levels the results of our calculations are compared with our measured σ and β values and with other works. The main mechanisms giving rise to the complex photon energy dependence of the β-parameters are analyzed
