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.

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. |
