Comment
Rec. value is from Rei02. Added value at kT= 5 keV from normalized energy dependence of jendl40 (f=1.04). Isomeric ratio at kT= 30 keV is IR= 0.098 (Bee91).

Original:MACS [<σ v>/vT] (mb) for kT=30 keV, based on the published cross sections except where indicated otherwise.
Renorm:MACS [<σ v>/vT] (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:
dRenormalized 2017 based on updated Au measurement
eEvaluated value taken directly from the reference
sSemiempirical estimates given in the reference
tTheoretical value
cDirectly quoted from the reference itself
