E(level): From least-squares fit to Eγ data, assuming 1 keV uncertainty in Eγ when not stated
Jπ(level): For high-spin (J>3), assignments are based on band assignments and generally supported by multipolarity assignments from DCO and γ(θ) data. Assignments are given in parentheses where arguments for firm assignments are lacking
E(γ): From 76Sr ε decay for low-spin (J<3). For high-spin (J>3) values are from 40Ca(40Ca,3pnγ):E=128 MeV when listed with uncertainties, otherwise from 40Ca(40Ca,3pnγ):E=165 MeV. Exceptions are noted
I(γ): From 76Sr ε decay for low-spin (J<3). For high-spin (J>3) values are from 40Ca(40Ca,3pnγ):E=128 MeV. Exceptions are noted
M(γ): Assignments are based on DCO values and γ(θ) data for selected transitions. ΔJ=1,D+Q are most likely M1+E2, and ΔJ=2,Q most likely E2 transitions, as listed in 1995Ha13, and consistent with band structures. However, in the absence of polarization, internal conversion or other supporting data, evaluators prefer to list mult=D+Q for ΔJ=1 or 0 and mult=Q for ΔJ=2 assignments. Multipolarities in square brackets are assumed from ΔJπ.
