Abstract
We report on a photoemission study (XPS, UPS) of the evolution of the electronic Structure with cluster size of Ni(n), Pd(n), Pt(n)(n=1-15) mass-selected clusters deposited in submonolayer quantities on a Ag(11 0) single crystal surface. The monodispersed clusters display individu al discrete electronic structure features of the Ni3d, Pd4d and Pt5d e mission. With increasing cluster size the increasing splitting between the bonding-like and antibonding-like d-states reflects the molecular interaction. The shift of the center of gravity of the d-state spectr um towards the Fermi energy and its concomittant broadening indicate t he trend to transition-metal formation.
