Available isotopes for Bromine (Z=35)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
79Br 80Br
Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
New recomm. value is from WBK86b (normalized by 683/657= 1.04) and HKU08b (normalized by by 632/586= 1.0785) to correct for new 197Au cross sections. MACS vs. kT table from energy dependencies of jeff32 which fits the data perfectly, and normalized energy dependencies of endfb71 and jendl40. Additional uncertainties for MACS vs. kT tables from differences between evaluations. Recomm. partial cross section to isomer is deduced from isomeric ratio IR=0.274 HKU08b.
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: WBK86b,HKU08b,jeff32,endfb71,jendl40 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: Reference: Year: SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 108 cm3/mole/s, including SEF Chart of nuclei
Isotope: Bromine
