Abstract

Photoionization of the 5p6 shell in xenon leaves the ion in either the 5p⁵(²P_3/2) or np⁵(²P_1/2) state. Measurements of the ²P_3/2 : ²P_1/2 branching ratio are reported within the Xe 5s5p⁶6p(¹P₁) resonance and fitted to a new theoretical expression. The maximum value of the ratio as determined by a two-parameter fit of theory to experiment is 8.8 ± 0.5 within the resonance, almost six times the nearly constant value of 1.55 found outside any resonance.
