The relative partial photoionization cross sections sigma(i) and photoelectron angular distribution parameters beta(1) are measured for all possible final ionic states of Br+ between the P-3(2) and S-1(0) thresholds. The decay patterns of the autoionizing 4p(4 3)P(1,0) nl, 4p(4 1)D(2) nl, and 4p(4 1)S(0) nl Rydberg series arising from the 4p ins,md excitations are observed at the fine-structure level in all available channels. For each Rydberg series, the energies, quantum defects, and photoelectron angular distribution parameters are determined, as well as the widths and shape parameters of the low-lying members. Relative total cross sections are derived from the partial cross sections and from ion-yield measurements over the lowest members of the P-3(1,0) and D-1(2) series. All major spectroscopic and dynamic properties of these series are reported for this open-shell atom. Conclusions are drawn from the comprehensive data sets in comparison with other halogen atoms and the neighboring closed-shell rare gas atoms. Our results, encompassing the entire autoionization regime, are compared with other experimental data and theoretical calculations, where available.
