Available isotopes for Sodium (Z=11)
22Na 23Na
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
22Na 23Na
Cross sections do not include stellar enhancement factors! * only theoretical data available History
(Version 0.0 corresponds to Bao et al.) Comment
New dataset. No experimental data available. Recommended value is calculated from evaluated libraries. Assumed 25% uncertainty. The TENDL-2015 predictions seems to overestimate the cross section by 2-3 orders of magnitude.
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,endfb71 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: 2014 X-factor: SEF (Stellar enhancement factor): Reference: Year: Comment: Please note: SEF for this element have not been calculated but are expected to be close to 1. Rate: Reaction rate NA<σv> given in 106 cm3/mole/s, including SEF Chart of nuclei
Isotope: Sodium
