Q(β-)=11428 keV 6S(n)= 2622 keV 6S(p)= 1.71×104 keV SYQ(α)= -1.19×104 keV SY
Reference: 2012WA38

General Comments:

Production: 238UC-graphite + p, E(p)=600 MeV, mass separation; large-volume HPGe γ detector, 4π long detector for neutrons, pulsed beam; measured β-n growth and decay curves; determined T1/2 and %β-n (1991Kr15).

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔQ(β)=360, ΔS(n)=340, ΔS(p)=670, ΔQ(α)=590 (2003Au03).

Q-value: Q(β-n)=4940 320 (from systematics, 2003Au03).
