Abstract

The self-energy part of the quasihole Green function of an atom is used to calculate the spectral density of photoelectrons with allowance for many-electron correlations. A number of relationships is established between the Hartee-Fock and exact energies of quasihole states and the intensities of the corresponding photoelectron peaks. It is shown that allowance for many-electron correlations does not affect the resultant intensity or the 'center of gravity' of the photoelectron spectrum. (7 References).
