E(level): Deduced by the evaluator from a least squares fit to the γ-ray energies. Eγ related to uncertain placement and expected ones were ignored.

Jπ(level): Spins and parities for levels above 1188 keV are from (HI,xnγ) data. These assignments are based on γ angular distribution, linear polarization, conversion electron measurements, and transition strengths.

T1/2(level): All excited states’ half-lives are from (HI,xnγ) data.
