The influence of the number of unoccupied 3d states on the L3M4,5M4,5Auger spectrum of Ni

Abstract

The Ni L_2,3M_4,5M_4,5 Auger spectra, the conduction band X-ray photoemission spectra and the Ni 2p_3/2 X-ray photoemission spectra have been measured for Ni, Ni₅₀Zn₅₀, Ni₂₀Zn₈₀ and Ni₅₀Al₅₀. The shape of the L₃M_4,5M_4,5 Auger spectrum changes as the band structure of the alloy changes in a way which agrees closely with the recent calculations of Treglia et al. (1981). The data support the conclusion of Treglia et al. that the number of unoccupied d states has a larger effect on the width of the Auger lines than the width of the 3d band.
