Hs. Chakraborty et al., Interchannel coupling in the photoionization of the M shell of Kr well above threshold: Experiment and theory - art. no. 042708, PHYS REV A, 6304(4), 2001, pp. 2708
Photoionization cross sections and asymmetry (beta) parameters for Kr 3s, 3
p, and 3d subshells have been measured and calculated in the 300-1300-eV ph
oton energy range. Good agreement between experiment and theory is found fo
r both cross-section branching ratios and beta parameters. Interchannel cou
pling 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 i
nterchannel coupling phenomenology far above threshold, found previously fo
r outer shells of Ne and Ar, is also operative for inner atomic shells.
