General Comments:

The isotope produced in natural Re(16O,xn) reaction (1987Va09). The ε decay, IT decay, and α decay studies (1984Va11, 1987Va09, 1991Va04, 1992Hu04) suggest population of three isomers; the 308S isomer corresponds to the g.s. of 196Bi with a probable Jπ=2+,3+.

Nuclear structure calculation: 1991Ch36.

Yield measurement in heavy ion reactions: 1985Hu06.

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