Abstract
Partial photoionization cross sections and angular-distribution asymmetry parameters were determined for Kr 3d photoemission using photon energies of 100 to 280 eV (to 800 eV for the asymmetry parameter). For the 3p subshell, the branching ratio relative to the 3d cross section and the asymmetry parameter were measured using energies of 280 to 800 eV. These results show good agreement with Hartree-Fock-theory predictions at all photon energies. The summed intensity of 4p→np satellites relative to the 3d main line was found to be approximately constant in the photon-energy range 180–280 eV, and the average asymmetry parameter for these shake-up states showed a marked increase over the same energy range.
