Excitation-energy dependence of the resonant Auger transitions to the 4p(4)(D-1)np (n=5,6) states across the 3d(3/2)(-1)5p and 3d(5/2)(-1)6p resonances in Kr

摘要

The energy dependencies of the intensities and angular distribution parameters beta of the resonant Auger final states 4p(4)(D-1)np (n=5,6) of Kr were determined experimentally in the excitation-energy region of the overlapping 3d(3/2)(-1)5p and 3d(5/2)(-1)6p resonances. The experimental results were compared with the outcome of multiconfiguration Dirac-Fock calculations. Combining experimental and calculated results allowed us to study interference effects between the direct and several resonant channels that populate the 4p(4)(D-1)np states. The inclusion of the direct channel was crucial in order to reproduce the observed energy behavior of the angular distribution parameters. It was also important to take into account experimentally observed shake transitions.
