Popis:	Electron emission spectra of metallic Ca, Sc, Ti and V excited by rare-gas-ion bombardment are presented. The spectra display distinctive atomic characteristics as well as solid-state structure due to M23VV Auger emissions. By energy considerations, we show that their main spectral features can be explained by atomic autoionizations of the excited metal atoms in 3p53dn+14s2 states with excitation energies less than the solid-state 3p ionization energy. The relative importance of the autoionization channels M23N1N1, M23M45N1 and M23M45M45 is investigated by comparing theoretically calculated spectra with the experimental spectra. Our work suggests that M23M45N1 transitions rather than super-Coster-Kronig M23M45M45 transitions dominate the decay channels.
