Last review: 1999
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
Procedure: 't' (The MACS from kT=5 keV to 100 keV are obtained from theoretical calculations with corresponding uncertainties between 25 and 50% in most cases.)
SEF (Stellar enhancement factor):
Reaction rate NA<σv> given in 108 cm3/mole/s, including SEF
