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

J^π(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).
