#) From γ-circular polarization of transitions which populate known L(d,p)=1 levels (1978Ve08)

@) From L-values and analyzing power (1973TyZZ)

&) From DWBA analysis of σ(θ) and Ay(θ) data

a) Adopted Jπ’s for all other levels are from L(d,p) data or from shell model calculations and level systematics in (HI,xnγ).

b) L=2 reported in ⁶⁴Ni(α,³He) is in disagreement with all other data.

*’) From log ft=5.1 in ⁶⁵Co β^- decay.

E(level): Levels with uncertainties |>10 keV are from ⁶⁴Ni(d,p) data. Other level energies are from a least-squares fit to Eγ data, except as noted. An Eγ uncertainty of 1 keV has been assumed by the evaluators where necessary in the performance of the least-squares fit.

E(γ): From ⁶⁴Ni(n,γ) E=th and ⁶⁵Co β^- decay, except for the 63γ which is from ⁶⁴Ni(d,pγ)

I(γ): Relative photon branching from each level are given. Data are from ⁶⁴Ni(n,γ) E=th, ⁶⁵Co β^- decay or (HI,xnγ)

E(level)	E(gamma)	Comments
63.37	63.36	M(γ): from α≈5 in (n,γ) mult=E1⁺M2 or M1⁺E2 with large δ or E2⁺M3 with small δ. RUL rules out M2 and known Jπ change rules out M1. Thus mult=(E2) or (E2⁺M3) with δ<1×10^-4.
