(Version 0.0 corresponds to Bao et al.) Comment
New rec. value is weighted average of MBB05 and WLK86. Uncertainty in MBB05 is only statistical, assumed 5% total uncertainty. New MACS vs. kT table is normalized average from recently evaluated databases (jendl40, endfb71, jeff32). TENDL-2015 is discrepant. There is an additional uncertainty introduced in the MACS vs. kT table from the deviation of the evaluations, which can be as high as 10% for kT= 5 keV.
Last review: December 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: MBB05,WLK86,jendl40,endfb71,jeff32 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 107 cm3/mole/s, including SEF Chart of nuclei
Isotope: Krypton
