E(level): For states connected by γ’s, E(level) are from Eγ and scheme by using least-squares adjustment procedure; the others are from 58Ni(d,α), (pol d,α), except as noted.

T1/2(level): From 54Fe(3He,pγ), ΔS(a) method, except as noted.

E(γ): From 54Fe(3He,pγ), except as noted.

I(γ): Relative photon branching from each level renormalized to 100 for the strongest branching. Values from 54Fe(3He,pγ), except as noted.
