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).
