Comment
Recommended value is from KSW93. Energy dependence is from recent evaluations (endfb71,jendl40) normalized to the recommended value. Uncertainty is deviation between both evaluations plus 3% uncertainty from KSW93. Isomeric ratio is IR= 0.111 at 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:
| c | Directly quoted from the reference itself |
| b | Calculated from smooth cross sections with model fit: ln(sigma) = a + a1 ln(E) + a2 ln^2(E) |
| e | Evaluated value taken directly from the reference |
| t | Theoretical value |

MACS:
Reference: KSW93,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.)
