Zusammenfassung, Abstract
The contributions of direct transitions [f\(A) over right arrow.(p) over right arrow \i] and surface emission [f\div (A) over right arrow \i] in angle-resolved photoelectron spectroscopy spectra can be varied considerably by changing the incidence angle of p-polarized light. Due to interference of both contributions line shape and asymmetry of certain peaks change dramatically as a function of light incidence direction. This effect has been studied in detail at an s.p band of copper and a photon energy of h omega =21.2 eV. Our experimental data can be explained quantitatively within a physically transparent model calculation, which supplies a criterion to distinguish between bulk direct and surface emission.
