Abstract
It is shown that strong-coupling theory explains semiquantitatively the angular-resolved photoemission data of NiO. A linear spin-wave treatment of a generalized spin-fermion model, derived for a slab of NiO, shows that a well developed sector of Zhang-Rice bound states coexists with reasonably damped oxygenlike quasiparticle states at large energies.Keywords
