Q(β-)=4.17×103 keV SYS(n)= 5.93×103 keV SYS(p)= 1.16×104 keV SYQ(α)= -2.9×103 keV SY
Reference: 2012WA38

General Comments:

Nuclide identified by 2000IcZZ and 2001AsZY (both studies have many of the same authors). α subsequent study by 2005Ic02 (again, from the same group) reports 3 γ’s associated with the decay and a T1/2 value. Produced via 15.5-MeV proton bombardment of a stack of 238U targets. Reaction products transported using a He-jet gas-flow system to an on-line isotope separator. Isotopic identification provided by observation of Eu K x-rays. 2001AsZY report T1/2 only. 2000IcZZ report nuclide identification but no other data.

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

Q-value: The estimated uncertainties (in keV) to Be associated with these Q values are as follows: for Q(β-), 590; for S(n), 590; for S(p), 710; and, for Q(α), 640. (2003Au03)
