1008016 008_O_016 ENDF/B-VII The (n,alpha0), (n,alpha) and elastic cross-section magnitudes
(MF=3, MT=2,107,800) were changed in December 2005 by Philip Page
(LANL) from the ENDF/B-VI MOD 3 Evaluation (discussed above).
The change made to the ENDF/B-VI MOD 3 version is that the
cross-sections of all the 16O(n,alpha0) data in the region of
laboratory neutron energy 2.4-8.9 MeV have been been reduced by
32%. The threshold is at 2.4 MeV. The total 16O n cross-section
is fixed, so that the difference is put into the elastic 16O n
cross-section (in the region 2.4-8.9 MeV). The 16O(n,alpha)
cross-section is also changed to reflect the new 16O(n,alpha0)
cross-section.
MF3 MT102:
Capture cross sections above the thermal energy were replaced
by the evaluation in JENDL-4. The total and non-elastic
cross sections were adjusted by the differences in the capture.
