Other reactions: ⁵⁵Mn(n,p), ⁵⁸Fe(n,α), ⁵⁶Fe(e,p), ⁵⁹Co(e,α), ⁵⁹Co(π^-,pt),(π^-,2d), and ⁵⁹Co(π^-,α), see 1985Zh06.

Levels: Evaluator notes that correspondence among levels in (d,p), (t,p), and (d,pγ) is not unambiguous.

Gammas: Evaluator notes that correspondence between γ rays from (d,pγ) and from other studies is not unambiguous. Evaluator regards γ rays from (d,pγ) as tentative.

Gammas: Unplaced γ’s are from ⁵⁴Cr(n,γ) E=th, except as noted.

Q-value: Note: Current evaluation has used the following Q record 2603.1 4 6246.26 1912506 15-7801.6 12 2003Au03
