COMPILATION
-----------
THE FOLLOWING MODIFICATIONS WERE MADE FOR JEF-1.
1) RESONANCE FORMULA WAS CHANGED FROM THE SINGLE-LEVEL BREIT-
WIGNER TO THE MULTI-LEVEL BREIT-WIGNER.
2) THRESHOLD ENERGIES OF MT=53, 54 AND 91 WERE CORRECTED TO
542.44, 903.74 AND 1529.7 KEV, RESPECTIVELY.
3) THE TOTAL AND TOTAL INELASTIC SCATTERING CROSS SECTIONS WERE
RE-CALCULATED FROM PARTIAL CROSS SECTIONS.
4) THE ANGULAR DISTRIBUTIONS (MF=4) WERE ASSUMED TO BE ISOTROPIC.

FILE INFORMATION
MF=2 MT=151 RESONANCE PARAMETERS FROM NEW BNL-325 REF.(3).
MF=3 MT= 1 TOTAL CROSS SECTION CALCULATED USING MOLDAUER
POTENTIAL REF.(4) FOR E@EH.
MF=3 MT= 2 ELASTIC CROSS SECTION FROM SIGT-SIGCAP-SIGIN FOR
E@EH.
MF=3 MT= 4,51,52,.,.,91 INELASTIC CROSS SECTIONS CALCULATED
USING COMNUC-3 REFS.(5,6).
MF=3 MT=102 NEUTRON CAPTURE EVALUATED USING METHODS (NCAP CODE)
IN REFS.(1,2) FOR E@EH. A 1/V COMPONENT WAS ADDED TO
GIVE THE 2200M/S CROSS SECTION OF REF.(3) FOR E EH.
THE CALCULATED RESONANCE INTEGRAL AGREES(TO WITHIN
1 SIGMA) WITH THE VALUE GIVEN IN REF.(7).
MF=3 MT=251 MUBAR CALCULATED USING MOLDAUER POTENTIAL REF.(4).
MF=3 MT=252 STI CALCULATED FROM MUBAR(MT=251).
MF=5 MT= 91 EVAPORATION SPECTRUM(LF=9) PARAMETERS OBTAINED USING
NCAP CODE REF.(2).
