Available isotopes for Ytterbium (Z=70)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
176Yb 177Yb
Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
No significant change in recommended cross section. New value is weighted average of JM08 and WVA98c
Last review: July 9th, 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: WVK98c 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: 1998 SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 107 cm3/mole/s, including SEF Isotopic mass chain
