Available isotopes for Lead (Z=82)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
208Pb 209Pb
Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
New rec. value and MACS vs. kT table is taken from recent evaluation (jendl40) which seems to be the only one to include the data from BCM97 and RAK04. Uncertainty assumed to be 10.7% as in BCM97.
Last review: April 2014 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: jendl40,BCM97 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: 2014 X-factor: Reference: Year: SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 103 cm3/mole/s, including SEF Chart of nuclei
Isotope: Lead
