Total absorption spectroscopy study of the β decay of ⁸⁶Br and ⁹¹Rb

RADIOACTIVITY ⁸⁶Br, ⁹¹Rb(β^-)[from U(p, F), E not given, radioactive beams purified by JYFLTRAP Penning trap at Jyvaskyla]; measured Eγ, Iγ, βγ-coin, total absorption gamma spectrum (TAGS) using Valencia-Surrey Total Absorption Spectrometer Rocinante at the IGISOL facility of the University of Jyvaskyla; deduced mean average energy for β particles and γ rays, β spectra, B(GT) strengths, impact of the investigated decays in the prediction of decay heat and antineutrino spectrum from nuclear reactors. Comparison with previous experimental data, with the evaluated high-resolution decay data in the ENSDF database at NNDC-BNL, and with quasiparticle random-phase approximation calculations.
