Abstract: Corrections to the wave functions of atomic electrons in hydrogen-like atom are calculated by using the Thomas-Fermi potential in the framework of perturbation theory. In this approach the interaction of electrons in atom is approximately taken into account. Corrections to wave functions are important for describing various processes involving electrons in multielectronic atoms. Cross sections of the photoelectric effect on the L-shell of the atom are calculated in the proposed approach with impurity for the admixture of K-shell states.

Keywords: photoeffect, Thomas - Fermi model, atomic shell.
