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

Most of the intensity belongs with the 136 level, and mult=E1 can be assigned to this placement. Placement from the 342 level involves Δπ=no
M(γ): In (n,γ) one has Eγ=109.614 4 with mult mainly E1 doubly placed from the 136 and 342 levels. The transition is also seen in α decay. From a comparison of the branchings in (n,γ) and α decay the intensity can be divided between the two placements. Most of the intensity belongs with the 136 level, and mult=E1 can be assigned to this placement. Placement from the 342 level involves Δπ=no
   163.26E(γ): In α decay one has Eγ=163.25 2 doubly placed from the 329 and 342 levels. Eγ=163.29 5 is reported in (n,γ) with mult=M1+E2, and placed from the 342 level only. From a comparison of branchings from the two sources, all the intensity of the 163γ in α decay can be accounted for by placement from the 342 level

   352.46    52.60M(γ): 1990Ho02 assign mult=E2 in (n,γ), and the placement requires ΔJ=2, Δπ=no; however, the ce ratios suggest an M1 component. One gets δ=1.44 8, 0.27 3, and 0.93 7 from L1/L2, L3/L2, and M1/M2, respectively. M3/M2 gives δ>0.25
   417.641   417.60E(γ): Multiply placed with undivided intensity. In (n,γ) one has Eγ=417.60 6 with mult=M1 doubly placed from the 418 and 524 levels. Both placements involve Δπ=no
I(γ): Multiply placed with undivided intensity
M(γ): In (n,γ) one has Eγ=417.60 6 with mult=M1 doubly placed from the 418 and 524 levels. Both placements involve Δπ=no
