摘要

We have measured valence-band spectra of a thick Mn metal film deposited on Si(111) by means of resonant photoemission across the Mn 2p → 3d absorption edge. A resonant Raman-Auger signal is detected for excitation energies down to 3.8 eV below the Mn L_3 absorption threshold. This feature exhibits a crossover from the Raman to the normal Auger behavior at a photon energy close to. the Mn 2p photoemission ionization threshold. The resulting radiationless resonance Raman behavior gives rise to a signal equivalent to the 6 eV satellite in Ni, with energy at 3.3 eV below E_F. Moreover, the presence of many-electron effects is detected for the Mn spectral weight in the valence band, with a clear contribution of Mn-derived states at the Fermi edge.
