Correlation corrections to the energies and wavefunctions of atomic core levels

We present the results of a calculation of correlation corrections for inner one-electron atomic states, including the dependence of the correlation corrections on the number of outer electrons. Our method also yields the correlation corrections to the wavefunctions.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 11, pp. 95–99, November, 1976.
