General Comments:

Assignment: daughter 166Hf, chem. γ(166Yb) (1969Ar23); 169Tm(3He,6n), E(3He)=45-80 MeV, excit, γ(166Yb) (1974De09); 170Yb(p,5n), E(p)=52 MeV, γ(166Yb) (1974De09).

For hfs and isotope shift data, see 1998Ge13.

Other Reactions: 123Sb(48Ca,5nγ) (1990McZY): identified four rotational bands; details of results not given.

Levels: E(d,d) Level energy is dependent on the validity of the 163γ and 251γ transitions linking the Kπ=2- and ΔJ=2 bands; these gammas were reported in (30Si.3nγ) and (12C,5nγ) but not in (19F,5nγ).

Levels: band(a) Kπ=6+, α=1 (π 7/2[404])+(ν 5/2[642]) band. See comment on signature partner band.

Levels: band(b) Kπ=7-, α=1 (π 9/2[514])+(ν 5/2[642]) band (2000Le25). See comment on signature partner band.

Levels: band(d) Kπ=2-, α=1 (π 1/2[541])-(ν 5/2[642]) band (2000Zh51). α=1 sequence is observed only in (19F,5nγ). See comment on signature partner of this band.

Levels: band(e) Kπ=5+, α=1 (π 5/2[402])+(ν 5/2[642]) band (2000Zh51). See comment on signature partner of this band.

E(level): From least-squares fit to Eγ, assigning 1 keV uncertainty to data for which the authors gave no uncertainty.

Jπ(level): Values given without comment are based on deduced band structure. It should Be noted, however, that different authors may disagree on the spin of a given level, even when they agree on the configuration assignment. See detailed comments on the individual bands.

E(γ): From 159Tb(12C,5nγ), except as noted. Eγ data from (30Si,3nγ) are in excellent agreement; however, Eγ data from (19F,5nγ) are consistently lower by as much as 1.5 keV.

I(γ): Relative photon intensity normalized to 100 for strongest photon deexciting each level. From 159Tb(12C,5nγ), except as noted.

M(γ): From intensity balance in 159Tb(12C,5nγ), except as noted.

E(level): <r2>1/2(charge)=5.298 5 (2004An14). From (19F,5nγ) (2000Zh51).
Jπ(level): Assignments for the lowest energy levels are consistent with systematics for neighboring nuclides (1974De09). Based on low-energy structure of odd-odd Lu isotopes, the 7/2[404], 1/2[411] and 5/2[402] proton orbitals are expected to lie lowest in energy (and at almost the same energy) for n=95, with the 1/2[541] and 9/2[514] orbitals at somewhat higher energy. Unhindered allowed ε decay from the g.s. to a 166Yb level and a (ν 5/2[523]) g.s. for 165Yb support the inclusion of the (ν 5/2[523]) orbital in the g.s. configuration in this mass region, so low-energy 6-, 3- and 0- levels are anticipated based on the Gallagher-Moszkowski rule, with 1- and 3+ states a little higher in energy.
