Strong channels in the Xe, 5s, 5p satellite spectrum in the region of the Xe 5s Cooper minimum

Abstract

The Xe 5s, 5p satellite spectrum has been studied using synchrotron radiation. Results show the total intensity of the satellites to be more than seven times larger than the 5s5p^{6 2}S_1/2 intensity in the Cooper minimum where the 5s partial cross section is small. It is suggested that the observed strong channels will influence the behaviour of the angular asymmetry parameter beta for the Xe 5s transition, and their inclusion in a theoretical treatment will improve the prediction for the Xe 5s parameters.
