We report a synchrotron-radiation investigation of the satellite structures of the Ni L3M4,5M4,5 Auger spectrum in the Ni compounds Ni2Si and NiSi2. The line shape of the satellites is extracted and analyzed for both compounds and compared to the corresponding structures in Ni metal as reported in the literature for a set of increasing photon energies; the procedure used to analyze the Auger data is described. The spectra analysis allows us to study the evolution in the line shape and in the energy position of the satellite structures in connection with the different chemical environment. The physical origin of these structures is discussed.

Abstract
We report a synchrotron-radiation investigation of the satellite structures of the Ni L3M4,5M4,5 Auger spectrum in the Ni compounds Ni2Si and NiSi2. The line shape of the satellites is extracted and analyzed for both compounds and compared to the corresponding structures in Ni metal as reported in the literature for a set of increasing photon energies; the procedure used to analyze the Auger data is described. The spectra analysis allows us to study the evolution in the line shape and in the energy position of the satellite structures in connection with the different chemical environment. The physical origin of these structures is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
