一致地被量子井态的标准描述所解释~QWS！基于相移量化。对于覆盖率小于5毫升的薄膜，没有观察到如此明确的QW。计算了外延Ag~111！的量子点的相移、能量色散和厚度-能量关系。电影是始终如一地衍生出来的。量子点的光电子能谱显示出两种不同类型的光能依赖关系：在hn55-15 eV处有振荡位移，而在hn 520-25 eV处没有这样的位移。这可以用光电发射过程中不同的终态来解释。
are consistently interpreted by a standard description of the quantum-well states ~QWS’s! based on phase-shift quantization. No such well-defined QWS is observed for the films with a coverage less than;5 ML. The phase shift, the energy dispersion, and the thickness-versus-energy relation of the QWS’s of the epitaxial Ag ~111! films are consistently derived. The QWS’s in photoemission spectra show two distinctive types of the photonenergy dependence in their binding energies; the oscillatory shifts for hn55 ‐ 15 eV and no such shift at hn 520‐ 25 eV. This can be explained in terms of the different final states in the photoemission process.
