Available isotopes for Argon (Z=18)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
39Ar 40Ar
Cross sections do not include stellar enhancement factors! * only theoretical data available History
(Version 0.0 corresponds to Bao et al.) Comment
No experimental data. New rec. value is from JEFF-3.2 which uses an older prediction from the TALYS code. Assuming 25% uncertainty. The TENDL-2015 predictions seems to overestimate the cross section by 2 orders of magnitude (similar behaviour seen with 41Ar). However, this recommended value is lower than its even-N neighbors, which is unusual. More investigation needed.
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: jeff32 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.) Year: 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: Argon
