The ratio of the 3103800400009 intensities of this gamma-ray for fhe two separations 3103800400010 is proportional to the ratio of the cross section: 3103800400011 58Ni(n,np)57Co/58Ni(n,2n)57Ni. The measured ratio was 3103800400012 found to be 4.2, with a cousistency of +-10%. 3103800400013 Cross section for the 58Ni(n,x)57Co was derived 3103800400014 from this ratio. 3103800400015 ENDBIB 13 0 3103800400016 NOCOMMON 0 0 3103800400017 DATA 3 1 3103800400018 EN DATA DATA-ERR 3103800400019 MEV B B 3103800400020 1.4100E+01 1.6000E-01 4.0000E-02 3103800400021 ENDDATA 3 0 3103800400022 ENDSUBENT 21 0 3103800499999 ENDENTRY 4 0 3103899999999
