1002003 002_He_003 ENDF/B-VII CONVERTED FROM ENDF/B-VI BY NNDC OCT 2004 New capture cross sections were evaluated with the EDA code.
The ENDF/B-VI evaluation is strictly 1/v, going through a low
thermal value, whereas the data indicate a higher thermal value,
and resonance structure around 2 MeV. This fit also had data in
the 4He(gamma,n) direction that indicated a much higher cross
section in the MeV region, and that is the reason why the new
evaluation looks overshooting the experimental 3He(n,g) data
in the MeV region. The differences in the new and old capture
cross sections was added to the total cross sections. G. Hale (Apr. 2011)
