Additional Level Data and Comments:
E(level) | Jπ(level) | T1/2(level) | Comments |
0.0 | 0+ | 29.5 s 4 % β- = 100 | E(level): Poor fit in level scheme; level-energy difference=3664.70. yrast STRUCTURE. |
659.15 | 2+ | 16.4 ps 32 | E(level): Poor fit in level scheme; level-energy difference=3664.70. yrast STRUCTURE. |
1742.59 | (4+) | E(level): Poor fit in level scheme; level-energy difference=3664.70. yrast STRUCTURE. Jπ(level): As proposed in 1999Ma21 and 2004Po06 from systematics of decay of 8+ isomers in n=48 isotones from 80Ge to 94Pd. The parentheses have been added by the evaluator. | |
2978.35 | (6+) | E(level): Poor fit in level scheme; level-energy difference=3664.70. yrast STRUCTURE. Jπ(level): As proposed in 1999Ma21 and 2004Po06 from systematics of decay of 8+ isomers in n=48 isotones from 80Ge to 94Pd. The parentheses have been added by the evaluator. Spin for most levels is likely to be <5 since direct population from 80Ga β- is indicated (probable J(80Ga g.s.)=3). Population of this state from 80Ga β- is unlikely if J=(3) for 80Ga g.s.; there might Be a high-spin isomer (possibly J=7) in 80Ga which may account for the population of (6+) and (8+) states. | |
3445.11 | (8+) | 2.95 ns 6 | Possibly νg9/2-2 isomer. E(level): Poor fit in level scheme; level-energy difference=3664.70. yrast STRUCTURE.
