E(level): From least-squares fit to Eγ.

Jπ(level): Values are based on transition multipolarities, branching ratios, alignments, orbitals expected near the Fermi surface and comparison with neighboring odd-A nuclides, except as noted. They are consistent with values proposed in (90Zr,nγ) but the evaluator has added parentheses for Jπ values shown as definite in 2002Ko09 because those relied, in part, on a definite Jπ=7/2- assignment for the 179Hg g.s.

M(γ): Assigned by evaluator based on γ(θ) and/or γ anisotropy ratio in 90Zr(90Zr,nγ), except as noted. Additionally, Δπ=(no) is assigned to all intraband transitions.
