Abstract
Buried interface states in Ar/Cu100 were studied by means of one and twophoton photoemission experiments With increasing Ar overlayer thickness a transition from broad electron scattering resonances in the Ar conduction band into a hydrogenlike series of quasibound states at the Ar/Cu interface was observed The thickness dependence of energies and lifetimes is compared to theoretical resonance positions and linewidths derived from a parameterized onedimensional potential
