Inner-shell ionization cross sections when the Sommerfeld-Maue wavefunction is used

Inner-shell ionization cross sections of silver and gold have been calculated from a result which uses the relativistic Sommerfeld-Maue wavefunction for the ejected electron. The results have been compared with the results of Das (see ibid., vol.7, 923 (1974)), which use the non-relativistic Coulomb wavefunction for the ejected electron. The comparison shows that there is only a few percent lowering in total cross section under these improved calculations and the overall trend of the curves for total cross section and the conclusion of Das are maintained.
