Total absorption γ-ray spectroscopy of the β- delayed neutron emitters ⁸⁷Br, ⁸⁸Br, and ⁹⁴Rb

RADIOACTIVITY ^87,88Br, ⁹⁴Rb(β^-)[from U(p, F), E=25 MeV]; measured β-gated Eγ, Iγ, total absorption γ spectra (TAGS) using Rocinante TAS, IGISOL mass separator and JYFLTRAP Penning Trap at the University of Jyvaskyla cyclotron facility. ⁸⁷Kr, ⁸⁸Kr, ⁹⁴Sr; deduced Iβ, β feedings, average γ- and β-decay energies, gamma-to-neutron branching ratio, reactor decay heat impact, reactor antineutrino spectrum impact. Comparison with previous data, and with Hauser-Feshbach calculations. Tables of the β-intensity distributions deduced in this work are supplied in supplementary file.
