Excited states in ⁸⁷Br populated in β decay of ⁸⁷Se

RADIOACTIVITY ⁸⁷Se(β^-)[from Th(p, F), E=25 MeV using the IGISOL technique, then separated on a dipole magnet and JYFLTRAP Penning trap setup]; measured Eγ, Iγ, γγ-coin using an array of six high-resolution Ge detectors with thin carbon windows at the University of Jyvaskyla. ⁸⁷Br; deduced levels, J, π, β feedings, logft values, configurations. ⁸⁷Se; deduced ground-state Jπ. Comparison with large-scale shell-model calculations, and with previous experimental results.
