Abstract
Photoemission indicates that the formation of the surface states (surface resonances) on the (111) face of ultrathin Pd overlayers on a recrystallized Nb foil commences with the deposition of the third atomic layer and is completely established at the full fourth layer. It also shows the formation of two resonant d states at submonolayer coverages, corresponding to the interaction of Pd d levels with the Nb bulk bands and to the Pd bulk d-band resonance, respectively.
