General Comments:

Levels: Band assignments are taken from 1998Sm08. The systematics on dynamic moment of inertia versus rotational frequency obtained from the experiment was compared with Total Routhian Surface calculations by 1998Sm08 for 127Pr, 129Pr and 131Pr. For the πh11/2 band, the tendency of increase of moment of inertia with decreasing neutron number is well reproduced by the calculation.

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

Q-value: Δ(Q(β-))=450, Δ(S(n))=277, Δ(S(p))=198 Δ(Q(α))=280 (2003Au03)
