English A detailed investigation of the Lα1,2 (L3→M4,5) and Lβ1 (L2→M4) x-ray satellite and hypersatellite structures in zirconium, molybdenum, and palladium atoms multiply ionized by impact with 278.6-MeV oxygen ions is reported. The x-ray spectra were measured with a high-resolution von Hamos bent crystal spectrometer. For the interpretation of the complex spectral features, relativistic multiconfiguration Dirac-Fock calculations were performed for all multivacancy configurations expected to contribute to the observed spectra. The data analysis clearly demonstrates that the spectra are dominated by structures originating from (L−1M−mN−n) satellite and (L−2M−mN−n) hypersatellite transitions corresponding to the radiative decay of the excited multivacancy configurations. The ionization probabilities of the L and M shell were determined from the data and compared with theoretical predictions from the geometrical model and the semiclassical approximation, using in the latter case both relativistic hydrogenlike and self-consistent Dirac-Hartree-Fock wave functions. The results support the independent electron picture of the multiple ionization. They also show the importance of using relativistic and self-consistent electronic wave functions for the L and M shells.
