Comment
New rec. value is from RDH12, 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 2.8% exp. uncertainty from RDH12. Note the 10% difference between the recent activation and the evaluations.

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:
| r | Recalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections |
| a | Calculated from resonance parameters with the formula from Ref. 45 |
| 1 | Including k from Ref. MaW81, where k is a correction factor which has been applied to the originally reported cross section |
| e | Evaluated value taken directly from the reference |
| s | Semiempirical estimates given in the reference |
| t | Theoretical value |

MACS:
Reference: RDH12,endfb71, jendl40,tendl15
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.)
