E(level): The level energies are from a least-squares adjustment to the adopted γ-ray energies.

Jπ(level): Spin-parity assignments are from 2000Ko16 (based mainly on angular distributions and anisotropy information) and/or 1999Da18 (founded on γ-γ angular correlations and internal conversion coefficients).

T1/2(level): From lifetime measurements using the recoil distance technique (1986Dr05) unless otherwise noted.

E(γ): Unless otherwise noted, the energy values are from 2000Ko16. Uncertainties of Δ(Eγ)=0.8 for Iγ<1, Δ(Eγ)=0.4 for 1|<Iγ|<10 and Δ(Eγ)=0.1 for Iγ>10, are estimates by the evaluators, based on values suggested in 2000Ko16. No uncertainties are reported by the authors of 1999Da18.

I(γ): Relative photon branching for each level are calculated from relative Iγ of 2000Ko16 or 1999Da18.

M(γ): From γ-ray angular distributions and anisotropy ratios (2000Ko16), mixing ratios δ(E2/M1) obtained from angular correlations (1999Da18), membership in γ ray cascades connecting levels in rotational bands, and character of interband transitions.
