Abstract
A strong, oscillatory photon energy dependence is observed for the int ensity of photoemission peaks due to quantum-well states in Na overlay ers on Cu(111). The measurements are made at low photon energies (hv < 8 eV) with Na films, which are between four and eight atomic layers t hick. The intensity oscillations are ascribed to the interference betw een the contributions to the outgoing wave associated with the two tai ls of a quantum-well state.
