New observation of the valence-band satellite in Ni(110)

Abstract

The valence-band photoemission of Ni(110) shows that the two-hole satellite appears at a constant binding energy of 6.0 eV away from the 3p\ensuremath{\rightarrow}3d resonance in accord with earlier results, but on resonance it shifts to \ensuremath{\sim}6.8 eV. Interpretation of this new result in terms of the singlet and triplet satellite states is proposed.
