%X We report on a detailed analysis of the evolution and spatial localization of quantum-well states (QWSs) in Ag layers on a Au(111) substrate by means of high-resolution photoelectron spectroscopy combined with model calculations based on a simple particle-in-a-box picture, the phase accumulation model, and density functional theory-based slab-layer calculations. Due to the finite electron escape depth we could link the photoemission intensity of the QWS to the simulated charge-density distribution and therewith confirm the calculated localization of these states. The first QWS starts to be localized within the Ag film at layer thicknesses >7 ML.
