1092238 092_U_238 ENDF/B-VI.8 MOD 3C - ADOPT JENDL-3.3 RESONANCE PARAMETERS AND MINOR
ADJUSTMENT OF (N,F) CROSS SECTION BELOW 4 MeV.
[3-06-2009]
1. We replaced the resolved and unresolved resonance parameters
with the parameters from the JENDL-3.3 evaluation/1/. We
modified the unresolved resonace parameters slightly to maintain
the ENDF/B-VII.0 unresolved energy cutoff of 0.01 MeV and to join
with the smooth cross sections above 0.01 MeV.
2. We adjusted the (n,f) cross section between 0.01 and 4 MeV to
give a higher cross section in the 1-2 MeV range, consistent with
systematics by Behrens/2/, and to smoothly join with the cross
section at the unresolved resonance region cutoff.
