| 0 | (2)- | 3.0 m 2 % β- = 100 | Configuration=ν9/2[505]~#π5/2[402], Kπ=2- (1976Ha39, 1974Ya02). |
| 119.12 | (3)- | 3- member of configuration=ν9/2[505]~#π5/2[402], Kπ=2- (1976Ha39, 1974Ya02). | |
| 162.10 | (0+) | Configuration=ν9/2[505]~#π9/2[514], Kπ=0+ (1976Ha39, 1974Ya02). | |
| 204 | (6-) | 3.1 h 2 % IT = 45.6 20 % β- = 54.4 20 | %IT: deduced by the evaluators from γ+ce intensity balances of γ transitions in 190Os from β- decays of the 3.0-min g.s. and the 3.1H isomer of 190Re in equilibrium (which means the total number of 190Re g.s. decays is equal to the total number of 190Re IT decays that feeds the g.s.) measured by 1974Ya02. Note that the relative γ intensities given as for 190Re isomer β- decay in 1974Ya02 are actually for the combination of 190Re isomer and g.s. β- decays, with the latter fed by the IT decays of 190Re isomer in equilibrium. See those decay datasets of 190Os for more details. E(level): %IT: deduced by the evaluators from γ+ce intensity balances of γ transitions in 190Os from β- decays of the 3.0-min g.s. and the 3.1H isomer of 190Re in equilibrium (which means the total number of 190Re g.s. decays is equal to the total number of 190Re IT decays that feeds the g.s.) measured by 1974Ya02.

| E(level) | E(gamma) | Comments |
| 119.12 | 119.12 | E(γ): from 190Re IT decay |
| 162.10 | 162.1 | E(γ): from 190W β- decay M(γ): From intensity balance arguments in 190W β- decay |
| 204 | 85 | E(γ): no isomeric transitions from the decay of this isomer have been reported in the literature. Transition to the 119, (3)- level is suggested by evaluators. If this transition has 100% I(γ+ce) branching, then B(M3)(W.u.)=0.000102 +12-11. E4 transition to the g.s., (2)- is also possible. |

2006Wa31 calculated total Routhian surfaces (TRS), which predicted oblate shapes induced by rotation-alignment of πh11/2~#νi13/2 pair of nucleons, with the oblate shape remaining yrast over a large range of angular momentum. Near-prolate high-K energy minima at h|w≈0 and near-oblate energy minima at h|w≈0.1 MeV are predicted from total Routhian surface (TRS) calculations in this work
