Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
Recommended cross section is value from URS09 renormalized with factor 1.5/2.6= 0.577 which accounts for the new weighted half-life of 2.60 (5) My from GR09 and WBB15. Value in v1.0 renormalized by f= 1.0785 (632 mb/586 mb) due to corrected Gold cross section from RaK88 for activations. MACS vs. kT table from URS09 extended to lower kT with NON-SMOKER due to its excellent agreement, including the new thermal cross section from HBD15 (1/v up to 1 keV).
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: URS09, RaT99 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: 2009,2016 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
Isotope: Iron
