Abstract / Artist's Statement
Absolute single photoionization cross-section measurements for Br+ are reported in the photon energy range of 17.0 to 32.4 eV. The merged beam technique which uses counter-propagating ion and photon beams was used for these measurements. One Rydberg resonance series is presented, which originates from the 3P2 parent ion state of Br+ and converges to the 2P3/2 final product ion state of Br2+. The ground state and meta-stable state ionization thresholds for Br+ and Br2+ are not yet confirmed, but are discussed. Analysis of each Rydberg series is calculated using quantum defect theory.

Photoionization Cross-Sections and Rydberg Resonance Identifications of Br+
