Abstract

The photodetachment cross sections, branching ratios, and angular-distribution asymmetry parameters have been calculated for F− and Br− in the relativistic random-phase approximation (RRPA) and modifications of the RRPA that allow for the inclusion of relaxation and core-polarization effects. Photodetachment cross sections are compared with experimental measurements to assess the effectiveness of the various approximations. The effects of core polarization are found to partially cancel relaxation effects.
