General Comments:

For states below 2740 keV, all data are from 57Cr β- decay and all states were observed in β- decay, (α,p), (α,pγ), and (t,p), except as noted. States above 2740 keV were observed in (α,p) only, except as noted. See also (n,pγ) for suggested states at 1061.3 and 1680.4 and associated gammas observed.

Other reactions:

59Co(μ-,pn) E=0 MeV: 1978Wy01 measured the production. 1978Wy02 measured T1/2.

E(level): Energies of states connected by γ’s were calculated using least-squares adjustment procedures, excluding uncertain transitions and other energies below 2740 keV from (t,p), except as noted. In addition to the levels labelled with xref=f for (d,3He), there are 14 broad peaks up to 7410 keV.

Jπ(level): From angular momentum transfer in (d,3He), except as noted. See β- decay, (α,p), (α,pγ), (t,p), (d,3He), (13C,3npγ), and (15n,2nαγ) for other proposed assignments.

T1/2(level): From DSAM in (13C,3npγ) and (15n,2nαγ), except as noted

I(γ): Relative-photon branching ratio from each level

M(γ): From comparison to RUL, except as noted

Additional Level Data and Comments:

E(level)Jπ(level)T1/2(level)Comments
   1072.9-   Jπ(level): L=even in (t,p).
   1227.5- > 0.35 ps Jπ(level): L=even in (t,p).
   1375.0-   Jπ(level): L=even in (t,p).
   1477-   Jπ(level): L=even in (t,p).
   1492.67-   Jπ(level): L=even in (t,p).
   1534.83-   Jπ(level): L=even in (t,p).
   1725.4-   Jπ(level): L=even in (t,p).
   1916-   Jπ(level): L=even in (t,p).
   1928-   Jπ(level): L=even in (t,p).
   19623/2+,5/2+   Note that L=2,4 in (t,p) suggesting the possibility of two distinct states. However, this was the weakest group observed in (t,p) and, therefore, assumption of relative s-state for transferred neutrons may not be valid.
   2008-   Jπ(level): L=even in (t,p).
   2772   May be the same as the state observed in (13C,3npγ) and (15n,2nαγ).
   3212   L=(3), 3.23-MeV, state may correspond to this or the following state.
   3482   L=3, 3.49-MeV, state in (d,3He) may correspond to the 3458, 3482, or 3542 states.
   4073   Energy of state could not be determined. From γγ data in (13C,3npγ) and (15n,2nαγ), a state with E|>3287 should be fed.
