Rec. value is from WVK06b. Perfect agreement with independent activation measurement of VDH07. Value at kT= 5 keV extrapolated from normalized averaged value of jendl40 and endfb71 (f(norm)= 1.28).

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:

r	Recalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
c	Directly quoted from the reference itself
e	Evaluated value taken directly from the reference
t	Theoretical value
