The L2,3MM Auger spectra of solid Ge have been measured using synchrotron radiation excitation. The most intense L2,3M4,5M4,5 Auger spectrum has been recorded with several photon energies around the 2p thresholds. As opposed to the 3p thresholds, no core-exciton-induced resonant Auger structures are found. The relative strengths of the different Auger groups have been determined and compared with calculations performed for Ge atoms. The relative intensities of Auger transitions within each Auger group are discussed. Some previously unresolved Auger transitions have been found. The linewidths of Auger transitions are observed to grow when the final-state holes locate in deeper M levels. This final-state broadening implies the presence of Auger cascades.

Abstract
The L2,3MM Auger spectra of solid Ge have been measured using synchrotron radiation excitation. The most intense L2,3M4,5M4,5 Auger spectrum has been recorded with several photon energies around the 2p thresholds. As opposed to the 3p thresholds, no core-exciton-induced resonant Auger structures are found. The relative strengths of the different Auger groups have been determined and compared with calculations performed for Ge atoms. The relative intensities of Auger transitions within each Auger group are discussed. Some previously unresolved Auger transitions have been found. The linewidths of Auger transitions are observed to grow when the final-state holes locate in deeper M levels. This final-state broadening implies the presence of Auger cascades.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
