Comment
New rec. value is normalized value (f=0.60) from average of evaluated libraries (endfb71,jendl40). Uncertainty at kT= 25 keV is from Bee91, otherwise from deviation of both recent evaluations. The isomeric ratio at kT= 25 keV is IR=0.204 (Bee91), assumed same ratio for kT= 30 keV.

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:
cDirectly quoted from the reference itself
eEvaluated value taken directly from the reference

MACS:
Reference: endfb71,jendl40,Bee91
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.)
