Atomic excitation as the result of inner-shell vacancy production

The probabilities of atomic excitation as a result of vacancy production in the 1s, 2s, and 2p shells have been calculated for elements with Z between 2 and 36 in the sudden approximation. Calculations were made with the Hartree-Fock-Slater wave functions. For rare gases, our results are in good agreement with those obtained by Carlson and Nestor [Phys. Rev. A 8, 2887 (1973)] with relativistic wave functions. The validity of the prediction of Carlson and Krause [Phys. Rev. 137, A1655 (1965)] by means of effective charge is discussed. Comparison with other theoretical calculations and the experimental data is made.
