Calculated angular distributions of photoelectrons using the orthogonalized planehyphen;wave approximation

摘要

The general equations for calculating angular distributions of photoelectrons within the orthogonalized plane‐wave approximation have been programmed for the electronic computer. Applications are described for the molecules CH4, H2O, and N2with incident photon energies from threshold to 1254 eV. Computed values of the asymmetry parameter &bgr; are compared to experimentally determined &bgr; values using HeI excitation. Large variations in &bgr; as a function of photon energy are obtained; possible interpretations are proposed.
