Abstract

Valence-band photoemission and its spin polarization of insulating Ni (${\mathrm{Ni}}^{2+}$:${d}^{8}$) compounds are studied by considering configuration interactions within the Ni-ligand cluster. It is found that the main lines, which have been assigned to $d$-hole (${d}^{7}$) final states, are due to final states where the $d$ hole is screened by a ligand-to-$d$ charge transfer and that the satellite contains significant ${d}^{7}$ character. Effects of these final-state interactions on the multiplet structure and the spin polarization are discussed.
