Abstract

Photodetachment cross sections have been calculated for the [Formula Presented] [Formula Presented] and [Formula Presented] subshells of the negative iodide ion, [Formula Presented] in the relativistic random-phase approximation (RRPA) and modifications of the RRPA that allow for the inclusion of relaxation and core-polarization effects. Total and partial photodetachment cross sections are compared with experimental measurements to gauge the effectiveness of the various approximations. Branching ratios and photoelectron angular-distribution asymmetry parameters are also presented. Core-polarization effects are found to partially cancel relaxation effects. © 2003 The American Physical Society.
