Abstract:
We present results on resonant inner-shell scattering in Gd across the M-5 threshold; the scattering channel with formally a 4p hole in the final state is studied. Two scattering channels are in competition: one at constant transferred energy and another at constant outgoing energy. The branching ratio of the process at constant transferred energy is about 5%. We isolate the many-body satellite structure of the formally 4p(3/2) final hole state and we discuss the importance of the multiplet splitting and of the super Coster-Kponig conversion of this state into another final state with two 4d holes. The results with resonant M-5 excitation are also compared with those of non-resonant excitation well above the M-4 threshold. Guidelines for future research are briefly presented.
