Additional Level Data and Comments:

0.0 | 4- | 6.70 d 3 % ε = 100 | μ=2.25 10 (1976Kr04,1989Ra17), Q=3.80 7 (1993HaZU) Δ<r2>(175Lu-172Lu)=-0.2 fm2 (1992Ne09,1993BoZR). E(level): Kπ=4- band. |
41.86 | 1- | 3.7 m 5 % IT = 100 | %ε+%β+<0.18 from Iβ+<0.015% (1967Dz10) and ε/β+=11.2 (1971Go40). Only Lu-x rays were seen in the photon spectrum. |
65.79 | (1)+ | 0.332 µs 20 | The band assignment is from (3He,d), (α,t) (1976El11). In 172Hf ε decay studies (1979To18,1966Ha23) this level was proposed as the bandhead of a Kπ=0+ band having configuration=((ν 7/2[633])(π 7/2[404])) but a level with this configuration will not be populated in proton transfer reactions (3He,d) and (α,t). Thus the Kπ=0+ assignment is unlikely if it is a common level populated in both studies. E(level): Kπ=1+ band. Jπ(level): From comparison of experimental and calculated cross sections in (α,t) and (3He,d). |
68 | (3-) | E(level): Kπ=3- band. Jπ(level): From comparison of experimental and calculated cross sections in (α,t) and (3He,d). | |
68 | (3+) | E(level): Kπ=1+ band. Jπ(level): From comparison of experimental and calculated cross sections in (α,t) and (3He,d). | |
109.41 | (1)+ | 440 µs 12 % IT = 100 | In 172Hf ε decay study, 1979To18 assigned this as 1+ bandhead of configuration=((ν 1/2[521])(π 1/2[541])) but calculations and experimental cross sections in (3He,d), (α,t) (1976El11) suggest E≈66 keV for this bandhead. |
109.85 | (2)+ | 2.30 ns 12 | In 172Hf ε decay study, 1979To18 suggest this level as 2+ member of the Kπ=0+ band with configuration=((ν 7/2[633])(π 7/2[404])); the 65.8 and 191.6 levels are assigned as the 0+ and 1+ members, respectively. But from (3He,d) and (α,t) results, the latter two levels are assigned (1976El11) different configurations. |
111.13 | (5-) | E(level): Kπ=4- band. | |
132 | (2+) | E(level): Kπ=1+ band. Jπ(level): From comparison of experimental and calculated cross sections in (α,t) and (3He,d). | |

179.85 | (1)+ | Probable configuration=((π 5/2[402])(ν 7/2[633])). | |
191.60 | (1)+ | ≤ 0.5 ns | 1976El11 assign this as 1+ member of a Kπ=0+ band having configuration=((ν 1/2[521])(π 1/2[541])) on the basis of energy calculation and experimental cross sections. 1979To18 assigned this as 1+ member of a Kπ=0+ band with configuration=((ν 7/2[633])(π 7/2[404])). α level with this configuration will not be populated in (3He,d) and (α,t). If this a common level populated in both studies, the latter configuration is unlikely. E(level): Kπ=0+ band. |
