(Version 0.0 corresponds to Bao et al.)
New rec. value is average from recent evaluations ( endfb71, jendl40). Uncertainty is deviation between both evaluations plus uncertainty as in WGV93.

Original:MACS [<σ v>/v T] (mb) for kT=30 keV, based on the published cross sections except where indicated otherwise.
Renorm:MACS [<σ v>/v T] (mb) for kT=30 keV for which the reference or standard cross section was meanwhile improved.
Type: The letters and numbers in the column labelled 'type' give information on how the cross section has been obtained:
c | Directly quoted from the reference itself | d | Renormalized 2017 based on updated Au measurement | b | Calculated from smooth cross sections with model fit: ln(sigma) = a + a1 ln(E) + a2 ln^2(E) | e | Evaluated value taken directly from the reference | t | Theoretical value |
