(Version 0.0 corresponds to Bao et al.) Comment
New rec. value is value from HKU08, 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 3% from HKU08. The activation value of DDF09 cannot be reproduced which might hint to a different energy dependence at higher energies as given in the present evaluations. Note that there is a discrepancy between recent activation measurements (DDF09,HKU08), the recalculation from WKM84, and the older TOF measurement from BeS75 which is considered in the older evaluations (endfb71,jendl40,jeff32).
Last review: June 2016 List of all available values
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:
MACS, SEF and Reaction Rates for different energies
MACS: Reference: HKU08,tendl15,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.) Year: 2016 X-factor: Reference: Year: SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 106 cm3/mole/s, including SEF Chart of nuclei
