0.0	1168 ± 47	-	-

(Version 0.0 corresponds to Bao et al.)

Rec. value is from evaluated library jendl40 which reproduces data of SMN07 in the unresolved resonance region. Uncertainty assumed to be ca. 3% as in SMN07.

Original:MACS [<σ v>/v_T] (mb) for kT=30 keV, based on the published cross sections except where indicated otherwise.
Renorm:MACS [<σ v>/v_T] (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
e	Evaluated value taken directly from the reference
s	Semiempirical estimates given in the reference
t	Theoretical value

MACS:
Reference: jendl40, SMN07
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.)
