    Summary
    An observation of the internal structure of the L-shell hypersatellite x rays resulting from the one-photon decay of L⁻² double-vacancy states in palladium multiply ionized by oxygen ions is reported. The Pd L₃→M4,5 x-ray spectrum was measured with a von Hamos high-resolution crystal spectrometer. The complex shape of the observed spectrum could be interpreted in detail using relativistic multiconfiguration Dirac-Fock calculations. The relative intensities of the measured x rays were found to be in good agreement with semiclassical approximation calculations using relativistic Dirac-Hartree-Fock wave functions.
