1.0	104 ± 26*	-	-

(Version 0.0 corresponds to Bao et al.)

New dataset in v1.0. No experimental value available, the rec. value is the average of the theoretical predictions from tendl15, endfb71,jendl40 with a 25% uncertainty.

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:
