E(level): From a least-squares fit to the adopted Eγ’s, except where noted otherwise
Jπ(level): The Jπ assignments start with the following model-independent data: Jπ(342)=5- based on HF(α)=2.01 7 from 5-. J(g.s.)=2, a measured value (see 1976Fu06) with π(g.s.)=+ from an E1, M1+E2, M1, M1 cascade from the 342 level. Jπ(136)=3- can then be established based on an M1+E2, M1+E2 cascade from the 342 level, and an E1 to the 2+ g.s. Jπ(179)=4- follows from an M1+E2 from 342 and an M1+E2 to 136, and Jπ(86)=3+ based on an E1 from 179 and an M1+E2 to g.s. The g.s., 86 level, and 136 levels are bandheads of Kπ=2+, 3+, and 3- bands, respectively. The 342 level is a Kπ=5- bandhead. Other adopted Jπ’s are based on band assignments of 1990Ho02, in addition to transition multipolarities as noted. In general, Jπ assignments of 1 to 4 are based on feeding by primary γ’s in thermal (n,γ), Jπ=1- to 4- assignments are based on feeding by primary γ’s in average resonance capture and Jπ=1- to 3- assignments are based on feeding by primary γ’s in average resonance capture and from a 2+ resonance.
E(γ): From (n,γ) and α decay. No details are available as to the γ energy involved in the measurement
I(γ): Branching ratios are from (n,γ), except where from α decay as noted, or where the level is populated only in α decay
