E(level): From least-squares fit (by evaluator) to Eγ’s.

Jπ(level): Spin and parity assignments are based on assumed rotational band structure. Specific arguments are given to individual levels.

E(γ): Except those noted, Eγ’s are weighted averages of values from 181Hf β- decay, 181W ε decay, 180Ta(n,γ), 181Ta IT decay, Coulomb Excitation, 176Yb(11B,α2nγ) and 181Ta(238U,238U’γ). Δ(Eγ)=0.3 keV assumed for those from 176Yb(11B,α2nγ) (1998Dr09); and Δ(Eγ)=1 keV assumed for those from 176Yb(11B,α2nγ) (1998Sa60) and from 181Ta(238U,238U’γ).
