| 0.0 | (7/2+) | 450 ms 50 % β- = 100 % β-n = 49 10 | t,β-n: extrapolated values based on properties of 133Sb and 135Sb (2002Sh08). |
2002Sh08: spallation of U with 1 GeV p. Observed 137Sn decay.
1998Do08, 1994Do08: 238U on Pb, 750 MeV/α. Fission products analyzed for α and Z with fragment separator. Determined production cross section.
Activity, T1/2=2.0 s 6, seen as a 235U fission product. Assignment to 137Sb by 1976OtZW, is not confirmed.
Q-value: Note: Current evaluation has used the following Q record 9300 SY3450 syst 2003Au03
Q-value: ΔQ(β-)=420,ΔS(n)=500 (syst,2003Au03)
Q-value: Q(β-n)=6100 400 (syst,2003Au03)
