General Comments:

Levels: Possible existence of a high-spin 16.7-min isomer in 131Sb was proposed by 1988Go19 on the basis of observation of 434γ and 657γ. In a subsequent erratum, the authors retracted this claim because the same two γ rays had earlier been assigned to 129Sb isomer by 1982Hu09, although, 1987St23 did not report these two γ rays from the decay of 129Sb isomer. The origin of the two γ rays seen by 1988Go19 remains uncertain

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