Comment
New rec. value is value from HKU08, renormalized by 632 mb/586 mb = 1.0785, and recalculated with normalized energy dependencies of tendl15,endfb71,jendl40. Uncertainty is the deviation between different evaluations plus 3% from HKU08. The activation value of DDF09 cannot be reproduced which might hint to a different energy dependence at higher energies as given in the present evaluations. Note that there is a discrepancy between recent activation measurements (DDF09,HKU08), the recalculation from WKM84, and the older TOF measurement from BeS75 which is considered in the older evaluations (endfb71,jendl40,jeff32).

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:
rRecalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
cDirectly quoted from the reference itself
aCalculated from resonance parameters with the formula from Ref. 45
eEvaluated value taken directly from the reference

MACS:
Reference: HKU08,tendl15,endfb71,jendl40
Procedure: 'e+t' (The MACS from kT=5 keV to 100 keV are derived from calculated cross sections, which are then normalized to experimental data, e.g. to the values at kT=25 keV obtained in activation measurements. In these cases the uncertainties should be linearly increased below 25 and above 30 keV to reach about 30% at the extreme kT values.)
