The [ital K][alpha] and [ital K][beta] x-ray spectra of palladium and lanthanum bombarded by 5.5-MeV/amu [sup 16]O ions were measured with a high-resolution transmission crystal spectrometer. The observed complex structure of the [ital K][alpha][ital L][sup 0] and [ital K][beta][sub 1,3][ital L][sup 0] lines consisting of many [ital M] satellites was analyzed by means of theoretical line profiles based on multiconfiguration Dirac-Fock calculations. The average [ital M]-shell and [ital M]-subshell ionization probabilities in near-central collisions are determined. The experimental results are compared to the predictions of the semiclassical-approximation theory. The agreement is much improved by using Dirac-Hartree-Fock (DHF) wave functions instead of screened relativistic hydrogenic wave functions. The importance of DHF wave functions in the calculation of the [ital M]-shell ionization probabilities is illustrated with other examples.
