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 2161.6 155843.15 85641.2 11309 3 2011AuZZ

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
