E(level): Poor fit in level scheme; level-energy difference=3664.70. yrast STRUCTURE.
   659.152+ 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.

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.
