Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
New rec. value is taken from WBB16. This paper uses a "best fit" to the 152 keV resonance. A remeasurement of this cross section with TOF methods is desired to confirm this result.
Last review: April 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: WBB16 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: Please note: X-factors for this element have not been calculated but are expected to be close to 1. SEF (Stellar enhancement factor): Reference: Year: Comment: Please note: SEF for this element have not been calculated but are expected to be close to 1. Rate: Reaction rate NA<σv> given in 102 cm3/mole/s, including SEF Chart of nuclei
Isotope: Carbon
