Q(β-)=13490 keV SYS(n)= 1590 keV SYS(p)= 17940 keV SYQ(α)= -10370 keV SY
Reference: 2021WA16

General Comments:

1997Be70, 1997Be12: a total of 11 events assigned to 89Ge were identified in 9Be(238U,F),E=750 MeV/nucleon from measured fission fragment yields with a fragment separator (FRS) at GSI using time-of-flight technique, with a time of flight of 300 ns.

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

Q-value: Estimated uncertainties (2021Wa16): 500 for Q(β-), 570 for S(n), 640 for S(p) and Q(α)

Q-value: Q(β-n)=9340 450, S(2n)=5590 500 (syst,2021Wa16). S(2p)=35250 (theory,2019Mo01). Q(β-2n)=1268 450 (syst) deduced by evaluator from mass excess values in 2021Wa16.

Only β- decay is possible, followed by delayed neutron emission, thus 100% β- decay is assigned by inference.
E(level): Only β- decay is possible, followed by delayed neutron emission, thus 100% β- decay is assigned by inference.
