Available isotopes for Sulfur (Z=16)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
33S 34S
Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
Rec. value is from recent JEFF-3.2 evaluation taking the 6.5 % uncertainty from AHM75. Discrepance to previous evaluations which rely on data from MDH81 and a conference proceeding from 1981 and seem not to include all data from AHM75.
Last review: April 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: AHM75,jeff32 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: 1975,2016 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: Sulfur
