Abstract

The angular distribution of the Kr 4p photoelectrons was investigated in the photon energy range of the (3d)-1→np resonant excitations. The experimental dipole (β) and nondipole (γ and δ) anisotropy parameters were determined for the spin-orbit components of the Kr 4p shell. A simple theoretical model was developed for the description of the photoionization and excitation processes. An interference effect was observed between the direct photoionization and the resonant excitation participator Auger decay processes in the photon energy dependence of the experimental anisotropy parameters.
