79Br 80Br
Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
New recomm. value is weighted average of WBK86b and HKU08b.
New recomm. partial cross section to isomer is deduced from isomeric ratio IR=0.274 HKU08b. Last review: April 23rd, 2009 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: WBK86b,Mac88a,HKU08b 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: 1988,2008 SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 108 cm3/mole/s, including SEF Isotopic mass chain
