Comment
New rec. value is weighted average of BKK88a, Mac82d, and MSN83. Note the discrepancy to the values of BRW94 and BBM90, as well as between the evaluations. The MACS vs. kT table is scaled from jendl40 which agrees perfectly with the recommended value. Uncertainties are 2.9% for kT= 30 keV as in Mac82d, and then extrapolated to the value of 10-20% from the covariance data at kT= 5 and 100 keV. Isomeric ratio at kT= 30 keV is 0.052.

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)

MACS:
Reference: BKK88a, Mac82d, MSN83, 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.)
