MF=2 MT=151 NO RESONANCE PARAMETERS GIVEN EXCEPT AP.
MF=3 MT= 1 TOTAL CROSS SECTION CALCULATED USING MOLDAUER
POTENTIAL FROM REF. (4) FOR E .GT. EH.
MF=3 MT= 2 ELASTIC CROSS SECTION FROM SIGT-SIGCAP-SIGIN FOR
E .GT. EH, FROM 4PI*AP**2 FOR E .LT. 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 .GT. EH. A 1/V COMPONENT WAS ADDED TO
GIVE THE 2200 M/S CROSS SECTION OF REF.(3) FOR E .LT. EH
LOW ENERGY CAPTURE ALSO ADJUSTED TO GIVE RESONANCE
INTEGRAL(TO WITHIN 1 SIGMA) OF REF.(7).
MF=3 MT=251 MUBAR CALCULATED USING MOLDAUER POTENTIAL REF.(4).
MF=3 MT=252 STI CALCULATED FROM MUBAR (MT=251)
MF=4 MT=2 ANGULAR DISTRIBUTION ASSUMED ISOTROPIC
MF=4 NON-ELASTIC A.D. ASSUMED ISOTROPIC
MF=5 MT= 91 EVAPORATION SPECTRUM(LF=9) PARAMETERS OBTAINED USING
NCAP CODE REF.(2).
