General Comments:

2001Ko07: 141Pr(n,γ):

142Pr was produced, in addition to other isotopes, to explore the potential of using a small HPGe detector to obtain β|+ maximum energies. Q(β-)=2154 3 as compared to 2162.5 5 (2003Au03)

There have been no significant changes in this nuclide since its last evaluation.

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

Q-value: Q(β-n)=-7666 3, Q(εp)=-8143 4 2011AuZZ

Q-value: Values in 2003Au03: Q(β-)=2162.5 15, S(n)=5843 15, S(p)=5641.2 11, Q(α)=307 3 Q(β-n)=-7666 3, Q(εp)=-8143 4
