E(level): From least-squares fit to adopted gammas if γ decay is observed. Other level energies are from (p,p’).

Jπ(level): Jπ for the levels seen in (α,2nγ) are based upon γ(θ), excit, multipolarity of transitions.

T1/2(level): From Doppler-shift attenuation and recoil-distance technique in (α,2nγ), unless indicated otherwise.

E(γ): Most precise value from β- decay, β+ decay, (n,γ), (α,2nγ), or weighted average of the most precise values.

M(γ): From γγ(θ) in (n,γ) and β- decay (31.76 min), γ(θ), α(K)exp, linear polarization measurements in (α,2nγ), unless indicated otherwise.
