Jπ(level): Syst. For n=82 nuclei and mults as noted. The mults of the cascading γ’s, with no observed crossover transitions, tend to confirm the assignments
E(γ): From 152Lu ε decay, unless otherwise noted
M(γ): From IT decay

| 2550.1 | 347.6 | E(γ): From IT decay (1982No13). No uncertainties have been assigned by these authors. From a comparison with the 313, 359, and 1531γ’s reported in ε decay, the evaluator has increased the energies from 1982No13 by 0.2~keV and has assigned an uncertainty of 0.3~keV |
| 2689.9 | 140.0 | E(γ): From IT decay (1982No13). No uncertainties have been assigned by these authors. From a comparison with the 313, 359, and 1531γ’s reported in ε decay, the evaluator has increased the energies from 1982No13 by 0.2~keV and has assigned an uncertainty of 0.3~keV M(γ): from IT decay |
| 2744.5 | 54.6 | E(γ): From IT decay (1995Ni10) |
