Comment
New rec. value is weighted average of BRW94, BKK88a, Mac82d, and MSN83. MACS vs. kT table is scaled from normalized energy dependencies of tendl15,jeff32,endfb71, and jendl40 (normalization factor f=0.974). Uncertainties are 3% at kT= 30 keV as in Mac82d, and then extrapolated to the standard deviation between the evaluations at kT= 5 and 100 keV. Isomeric ratio at kT= 30 keV is 0.046.

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
bCalculated from smooth cross sections with model fit: ln(sigma) = a + a1 ln(E) + a2 ln^2(E)
eEvaluated value taken directly from the reference

MACS:
Reference: BRW94, BKK88a, Mac82d, MSN83, tendl15, jeff32, 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.)
