  C  53Cr(t,p)  D  54Cr(n,γ) E=THERMAL
  E  54Cr(d,p)  F  54Cr(d,pγ)
  G  54Cr(pol d,p) 

General Comments:

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
