Interchannel coupling in the photoionization of the M shell of Kr well above threshold: Experiment and theory

Photoionization cross sections and asymmetry ({beta}) parameters for Kr 3s, 3p, and 3d subshells have been measured and calculated in the 300--1300-eV photon energy range. Good agreement between experiment and theory is found for both cross-section branching ratios and {beta} parameters. Interchanne...

Description
Summary:Photoionization cross sections and asymmetry ({beta}) parameters for Kr 3s, 3p, and 3d subshells have been measured and calculated in the 300--1300-eV photon energy range. Good agreement between experiment and theory is found for both cross-section branching ratios and {beta} parameters. Interchannel coupling among the channels arising from 3s, 3p, and 3d subshells is found to be necessary for quantitative accuracy of the theory. This shows that the interchannel coupling phenomenology far above threshold, found previously for outer shells of Ne and Ar, is also operative for inner atomic shells.
