For atoms with closed shells in their ground state, a Hartree-Fock (HF) equation is obtained for the electron moving in the field of an inner shell vacancy which decays through autoionization. In this equation, the following processes are taken into account : 1) change of the HF field of the remaining atom as a result of autoionization decay of the inner shell vacancy ; 2) interaction of the photoelectron with virtual Auger electron, thus the radial correlation in their movement is accounted for. The developed method is applied to study the L $_{\rm II.~III}$-photoexcitation in Ar atom.
