New rec. value and MACS vs. kT table is from WVK06b. Value at kT= 5 keV extrapolated from normalized value of jendl40 (f(norm)= 1.134). Isomeric ratio at E(n)= 75(25) keV is IR= 0.50 (2) WVK06b.

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:

d	Renormalized 2017 based on updated Au measurement
c	Directly quoted from the reference itself
e	Evaluated value taken directly from the reference
t	Theoretical value
