| 0 | (2-) | 106 ms 4 % ε = 29 3 % p = 71 3 |

Additional Level Data and Comments:
| E(level) | Jπ(level) | T1/2(level) | Comments |
| 0 | (2-) | 106 ms 4 % ε = 29 3 % p = 71 3 | α decay is not reported and is not expected to be appreciable, since such a transition would take place across the n=82 major closed shell (see, e.g., 1993Li34, 1995Ro39). E(level): α decay is not reported and is not expected to be appreciable, since such a transition would take place across the n=82 major closed shell (see, e.g., 1993Li34, 1995Ro39). |
The data on these levels are derived primarily from studies of their decay properties, with the levels themselves being the source material produced through various heavy-ion-induced reactions.
