57FE cL All data are from 1974Ti01 (Ge(Li)), except as noted.
57FE cG All data are from 1974Ti01 (Ge(Li)), except as noted.
57FE cL E Calculated using least-squares adjustment
57FE2cL procedures; 14.4|g not included in the adjustment.
57FE cL E(A),J From adopted levels. J|p are consistent with those used by
57FE2cL 1974Ti01 in deducing J|p({+57}Mn g.s.)=5/2- on basis of log| {Ift}
57FExcL arguments
57FE cL E(C) 1974Ti01 did not observe the gammas associated with the
57FE2cL 1265 and 1359 states in (n,|g). I|b<0.02
57FE cG M,MR From adopted gammas
57FE cG RI Relative to I|g(692|g)=1000. The |DI|g given by 1969Wa12
57FE2cG (Ge(Li)) were underestimated (priv.comm. from T. E. Ward to 1974Ti01).
57FE3cG I|g's from 1969Wa12 and 1974Ti01 agree within uncertainties,
57FE4cG except as noted
57FE N 0.0055 211. 1.0 1.
57FE cN NR from |SI|g(122|g,136|g)=16.5% {i64} based on
57FE2cN |b|g-coincidence data (1969Wa12) indicating that 83.5% {i64} of the
57FE3cN total |b{+-} decay does not go through the 122 and 136 gammas. Note
57FE4cN that E|b's and placement based |b|g-coincidence data are discrepant
57FE5cN with Q(|b{+-}) indicating a possible problem in normalization.

57FE cG E(A) Former |g-ray calibration energies from |e decay
57FE2cG (1971He20,1972He42). Used as internal calibration points by 1974Ti01.
57FE3cG See |e decay for current values
57FE cG E(C) From adopted gammas. Not observed by 1974Ti01 or 1969Wa12
57FE cG RI(E) From adopted branching ratios and I|g(1725|g)={ 30 {i2}}
57FE cG RI(D) From adopted branching ratios and I|g(460|g)={ 0.14 {i6}}
57FE cG E(B) Not observed by 1969Wa12
57FE cB IB Based on decay scheme presented with assumption that there
57FE2cB is no direct feeding of the g.s. |D(|g-normalization) added in
57FE3cB quadrature for I|b to states above { 136 keV}
57FE cB E(A) If present placement is correct, E|b's are discrepant with
57FE2cB adopted Q(|b{+-})

57FE cB 1963Va37 assigned E|b=1100 {i100}, I|b=18 to {+57}Mn |b{+-}
57FE2cB decay. It is extremely doubtful that this assignment is correct since

57FE cG RI 1974Ti01 noted that their measurement of
57FE2cG I|g(122|g)/I|g(136|g)=7.23 {i29} agreed with the branching ratio from
57FE3cG |e decay (1971Ko19), but differed from that of 1969Wa12, where
57FE4cG I|g(122|g)/I|g(136|g)=8.70 {i8}. The branching ratio in the adopted
57FE5cG gammas agrees with 1969Wa12.
