Valence-Band and Core-Level Photoemission Satellites in NiGa

Abstract

Photoemission studies of the valence-band and core-level satellites of NiGa are presented. The valence-band satellite is resonantly enhanced near the 3p threshold (h nu = 67eV), and its centroid position is photon energy dependent, which is in agreement with previous observations for elemental Ni. Surprisingly, the resonantly enhanced valence-band satellite in NiGa has about the same intensity as that for elemental Ni, even though the number of empty d- states contributing to the resonant enhancement is expected to be smaller in NiGa. Keywords: Ultra violet, X ray photoelectron spectroscopy, Two hole bound state, Resonance excitation, Nickel compounds, Gallium compounds.
