Measurement of the spin-orbit branching ratios and the angular asymmetry parameter in the region of the4s4p65presonances in krypton and the5s5p66presonances in xenon

Abstract

Variation of the ratio of partial photoionizaton cross sections R = sigma(/sup 2/P/sub 3/2/)/sigma(/sup 2/P/sub 1/2/) and the asymmetry parameter ..beta.. have been determined in the region of the 4s4p/sup 6/5p resonances in krypton and 5s5p/sup 6/6p resonances in xenon. In both cases these resonances are affected by the interaction with a configuration involving two excited outer p electrons. This admixture influences the number of resonances present, and the value of ..beta.. and R. Large variations in ..beta.. and R are observed in the region of these resonances.
