(Version 0.0 corresponds to Bao et al.) Comment
New rec. value is from MBB05. Uncertainty in MBB05 is only statistical.
Note: There seems to be a systematic discrepancy between the values from TOF measurements (MBB05, WLK86, RFH83) and from activation measurements (BSR02a/Bee91, KNA87, WBK86a). The weighted average from the 3 activation measurements is 3.8 mb, but the value for the 3 TOF measurements would be 4.9 mb. More investigation needed! 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 Procedure: 'e' (The Maxwellian-averaged cross sections (MACS) from kT=5 keV to 100 keV are obtained from experimental data; the relative uncertainties are similar to those quoted for the 30 keV data.) Year: 2004 X-factor: Reference: Year: SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 105 cm3/mole/s, including SEF Chart of nuclei
