✦ Synopsis

A new method of calculation of the atomic inner shell photoionization cross section is described. It allows us to find the profiles of the lines in the photoelectron and Auger spectra taking into account the final state interaction of the photoelectron with the field of a double-charged ion (this interaction is known in the literature as the post collision interaction). The amplitude of the ionization process is found as a solution of an inhomogeneous integro-differential equation of the Hartree-Fock type with appropriate boundary conditions. The non-iterative method of the solution of the boundary problem is considered. Examples of the calculations are discussed.
