Description

We present a comparison of recent experimental data and recent theoretical calculations of the photoelectron energy distribution curves for solid argon and krypton. These comparisons are significant in that they support the idea that the valence states of the solid rare gases are band like and of nonnegligible width (Ar is about 1.5 eV wide and Kr is about 2 eV wide). Furthermore, in order to obtain reasonable agreement between theory and experiment, the calculations needed were selfconsistent Hartree-Fock in nature and were corrected for both long range correlation effects (polarization) and short range effects (relaxation). (orig.)

Abstract (German)

Es werden experimentell bestimmte Energieverteilungskurven fuer Photoelektronen mit berechneten Energieverteilungskurven fuer festes Argon und Krypton verglichen. Diese Gegenueberstellung unterstuetzt die Annahme, dass die Valenzzustaende der festen Edelgase Bandcharakter haben, wobei die Baender eine nicht zu vernachlaessigende Breite haben (etwa 1,5 eV fuer Ar und etwa 2 eV fuer Kr). Um eine brauchbare Uebereinstimmung zwischen Theorie und Experiment zu erzielen, wurden selbstkonsistente Hartree-Fock Rechnungen zugrunde gelegt. Dabei mussten sowohl lang reichweitige Korrelationseffekte (Polarisation) als auch kurz reichweitige Effekte (Relaxation) als Korrekturen beruecksichtigt werden. (orig.)
