HISTORY
83-03 COMPILED BY K.SHIBATA FOR JENDL-2
MAIN PART WAS CARRIED OVER FROM JENDL-1 DATA EVALUATED BY
M.YAMAMOTO. DETAILS ARE GIVEN IN REF. /1/.
83-11 MF=2 WAS ADDED. THE TRANSFORMATION MATRIX GIVEN FOR MT=2 OF
MF=4.
84-12 RE-EVALUATED BY K.SHIBATA (JAERI) FOR JENDL-3
ELASTIC SCATTERING CROSS SECTION WAS RE-CALCULATED BELOW
100 KEV.
MU-BAR WAS ALSO RE-CALCULATED.
PHOTON-PRODUCTION CROSS SECTION WAS ADDED.
