General Comments:

Cross section data for 176Yb(α,xnγ): 1992Ro24 (E=threshold-84.3 MeV), 1983Ma32 (E=50-120 MeV)

Nuclear structure calculations: 1994Ze07, 1994Ze06, 1994Sa13, 1994Ja03, 1992Wu05, 1992Sa16, 1991Su08, 1991Ha11, 1991Ha09, 1991Ch49, 1989Hu05, 1988Ku21, 1987Ku24, 1987Ba82, 1984El04, 1981Mi07, 1980Xu01, 1980Ku01, 1980Du05, 1980An13, 1979Li04, 1979Ha44, 1978Ab07, 1977Mo03, 1976Ra04, 1976Mo31, 1974St06, 1972Wa14, 1972Sk04, 1972Pr17, 1971Gu20, 1971Fr02, 1964Ha44

Levels: g factor=+0.14 4 (1975Sk01) for levels above 8+, 1037 and T1/2≈0.5 ps. Technique: IMPAC

Levels: While the triaxiality in SD bands is not ruled out, it remains unclear whether the SD bands observed in 172Hf should be associated with a triaxial SD minimum as suggested by UC (ultimate cranker code) calculations or with a near-prolate SD minimum suggested by the CRMF calculations in 175Hf

Gammas: No linking transitions between SD bands were found, thus no indication of wobbling mode in these bands.

Q-value: S(2n)=16290 40, S(2p)=10215 25 (2012Wa38)

E(level): From least-squares fit to Eγ data, 0.2 or 1 keV uncertainty on Eγ values when not given

Jπ(level): For levels populated in (HI,xnγ) and/or (α,xnγ), ascending spins are assumed as the excitation energy increases. When no γ(θ) or γγ(θ) data are available, Jπ’s are tentative and are based on probable band assignments to levels observed in a cascade of γ-ray transitions. In such cases no Jπ arguments are given

The γ-ray branching ratios suggest that there are two separate levels within ≈0.2 keV near this energy, one populated in 172Ta ε decay and the other in (HI,xnγ) and (α,xnγ).
E(level): From (HI,xnγ). In 172Ta ε decay, the 871.2 γ-ray peak was seen as a wide structure and was interpreted (1973Ca10) as mixed with an impurity. It is possible that the broadening was partly due to 875γ. It is assumed that the 1503 level is the same in the two studies (172Ta ε decay and (HI,xnγ)). ΔJ=(1), Kπ=(6+) band.
