Available isotopes for Niobium (Z=41)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
95Nb 96Nb
Cross sections do not include stellar enhancement factors! * only theoretical data available History
(Version 0.0 corresponds to Bao et al.) Comment
No experimental value available, the rec. value is the average of the theoretical predictions from tendl15, endfb71,jendl40 with a 25% uncertainty.
Last review: 1999 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: tendl15,endfb71,jendl40,jeff30A 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: 2017 X-factor: Reference: Year: SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 107 cm3/mole/s, including SEF Chart of nuclei
Isotope: Niobium
