A comparison of experimental and theoretical photoelectron energy distribution curves for solid argon and krypton

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 non-negligible 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 the calculations needed were selfconsistent Hartree-Fock in nature and were corrected for both long range correlation effects (polarization) and short range effects (relaxation).
