Comment
New rec. value is average from recent evaluations (endfb71,jendl40), uncertainty is 10% as in KYM77 plus deviation between both evaluations. Partial cross sections to ground-state and isomer estimated by isomer-to-g.s. ratio at E(n)= 24 (5) keV of ChS66 and MSR73 to be M/G= 4.05. Uncertainties of partial c.s. estimated to be 30%. Isomeric ratio at kT= 30 keV is then IR= 0.80.

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: 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.)
