Strong quadrupole interaction between the krypton 4p photoionization and 3d resonant excitation channels

The angular distribution of Kr 4p photoelectrons was investigated experimentally in the photon energy range of the 3d−1 → np resonant excitations. The experimental dipole and non-dipole anisotropy parameters were determined for the spin-orbit components of the Kr 4p shell. An interference effect was...

Summary:The angular distribution of Kr 4p photoelectrons was investigated experimentally in the photon energy range of the 3d−1 → np resonant excitations. The experimental dipole and non-dipole anisotropy parameters were determined for the spin-orbit components of the Kr 4p shell. 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.
