L23MM RESONANT AUGER-SPECTRA OF MN IN KMNF3

The L23 absorption spectrum as well as the photoexcited normal and res onant L23MM Auger spectra of Mn in KMnF3 are studied using synchrotron radiation. The absorption spectrum is very similar to the analogical spectrum of MnF2. The multiple-hole final states strongly contribute t o the normal L23M23M23, L23M23M45, and L23M45M45 spectra. At the reson ance excitation, a crystal-field-affected spectator structure appears in the L23M23M23 spectrum and, probably, in the L23M23M45 spectrum. Th e origin of this structure is discussed.
