2010Oh02: 98Br nuclide identified in 9Be(238U,F) and Pb(238U,F) reactions with a 238U86+ beam energy of 345 MeV/nucleon produced by the cascade operation of the RBIF accelerator complex of the linear accelerator RILAC and four cyclotrons RRC, fRC, IRC and SRC. Identification of 98Br nuclei was made on the basis of magnetic rigidity, time-of-flight and energy loss of the fragments using BigRIPS fragment separator. Experiments performed at RIKEN facility. Based on α/Q spectrum and Z versus α/Q plot, five counts in one setting and 6 counts in another were assigned to 98Br isotope. See also 2010KuZV for production cross section values. (Q=charge state)

Q-value: Estimated uncertainties (2017Wa10): 500 for Q(β-), 570 for S(n)
Q-value: Q(β-) and S(n) from 2017Wa10. S(p) and Q(α) from 2019Mo01 (theory)
Q-value: Q(β-n)=11100 420, S(2n)=6230 500 (syst,2017Wa10). S(2p)=35530 (2019Mo01,theory). Evaluators deduce Q(β-2n)=8690 400, Q(β-3n)=3690 400 from mass values in 2017Wa10
