57MN c Measured |g's, |b's, 205.8|g(t), and |g|g- and |b|g-coincidences;
57MN2c Ge(Li), scintillator; rabbit and helium-jet systems. 83|g and 850|g
57MN3c obscured by contaminants from {+56}Cr and {+56}Mn.
57MN cL Decay scheme constructed from |g|g-coincidence and singles
57MNxcL data
57MN cG Identification made by T{-1/2} or coincidence relationships
57MN DB EAV CALCULATED BY EVALUATORS
57MN cL E Calculated using least-squares adjustment
57MN2cL procedures; good agreement with 1978Da04.
57MN DL E$UNCERTAINTY GENERALLY SMALLER THAN THE 0.4 KEV ESTIMATED BY 1978Da04
57MN2DL FOR THE LOWER STATES AND LARGER FOR THE HIGHER STATES
57MN cL J From adopted levels. Assignments suggested by 1978Da04 are
57MN2cL given under comments. These suggested assignments are based on log|
57MN3cL {Ift} and existence of |g's with the assumption that
57MN4cL J|p({+57}Cr)=3/2-. The argument for J|p({+57}Cr)=3/2- depends on the
57MN5cL transition to the 2186 state. The evaluators do not adopt this
57MN6cL argument since J(2186)=1/2 is based on a calculation (1978An10) in
57MN7cL (|a,p) and |D(log ft) does not permit the statement that the
57MNxcL transition is allowed.
57MN DB E ENERGY CALIBRATION BY MEANS OF OTHER KNOWN BETA SPECTRA
57MN2DB OBTAINED IN THE SAME BG MEASUREMENT
57MN cB IB Calculated from intensity balancing at each
57MN2cB state, except as noted; in good agreement with 1978Da04 although |DI|b
57MN3cB are generally higher here
57MN cG RI Relative intensity. Some I|g's had to be obtained from
57MN2cG the 83|g coincidence spectrum because of low intensity or interference
57MN3cG from other lines in the singles spectrum

57MN cN NR from |SI|g(1+|a) to g.s. and I|b(to g.s.)=74% {i12}

57MN cG CC Calculated using adopted E|g
57MN DG KC,LC: CALCULATED USING ADOPTED EG
57MN cG M,MR From adopted gammas
57MN cG M(A),CC(A)$Added on basis of comment by 1978Da04 that,
57MN2cG theoretically, there was 5% conversion for this |g.
57MN cB IB(A) The ratio of accumulated {+57}Cr to accumulated {+57}Mn
57MN2cB activity was obtained from the helium-jet run. |s({+57}Mn)/|s({+57}Cr)
57MN3cB was used to obtain the g.s. feeding. |DI|b also reflects the
57MN4cB uncertainty in the ratio of production |s's.
