General Comments:

89Br produced and identified in fission of 235U together with the measurement of half-life (1947Re02,1948Hu33,1959Pe28). Later studies of 89Br decay: 1966Si09, 1971Ch38, 1971Kr22, 1984Ew01, 1974Gr29, 1976Ru01, 1981Ho17, 1993Ru01 and several others with an interest in beta-delayed neutron decay of this isotope

Mass measurements: 2008Su19, 2007Ra23 (JYFLTRAP, Penning-trap method at IGISOL facility in Jyvaskyla)

Theoretical calculations: consult NSR database at www.nndc.bnl.gov/nsr/ or additional document records in this dataset for 14 primary references for half-life and β-n decay mode of 89Br.

Q-value: Q(β-n)=3346 4, S(2n)=10525 5, S(2p)=27234 4 (2021Wa16)
