摘要：

Photoelectron energy spectra reveal discrete valence-electron states in the range 0-220 meV above E(F) for 1-3 atomic layers of Na on Cu(111). Apart from a stepwise dependence on the number of atomic Na layers the energy of the quantum-well states depends in a gradual manner on how full the layer is. The states are as well defined in energy as comparable surface states producing peak widths (50-90 meV), which depend on temperature and coverage.
