Valence band photoemission has been measured in chromium silicide as a function of the photon energy near the absorption threshold. Evidence of resonant photoemission is observed for the valence band and the two-hole satellite. The threshold for normal Auger regime is 2.8 eV below the absorption peak and 0.8 eV below the binding energy, even lower than in pure Cr metal where it is already at extreme levels. The requirement for good resolution in photon energy relative to absorption width for the resonant Raman Auger to be observed is found to be less restrictive than expected.
