Q(β-)=-9.7×103 keV SYS(n)= 9.3×103 keV SYS(p)= 1.97×103 keV SYQ(α)= 5923 keV 4
Reference: 2012WA38

General Comments:

All data are from the α decay of 161W to 157Hf. See, also, the 165Os α Decay data set.

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

Q-value: Q(β-),S(n),S(p): the uncertainties assigned to these estimated values by 2009AuZZ are as follows: for Q(β-), 286; for S(n), 286; and, for S(p), 215.

Q-value: For Q(β-) and S(n), 2003Au03 report the following: for Q(β-), -9530 290; for S(n), 9120 290. 2003Au03 report the same values for S(p) and Q(α) as those listed by 2009AuZZ, although with somewhat different uncertainties.
