Available isotopes for Lead (Z=82)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
Cross sections do not include stellar enhancement factors!
(Version 0.0 corresponds to Bao et al.)
Recommended MACS30 is weighted mean from CDP06a and MCA97b. MACS vs. kT for kT=5-30 keV from CDP06a, from kT=35-100 keV previous values multiplied with 1.021.

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
Reference: MCA97b, KWW87, CDP06a
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: 1997, 2006
SEF (Stellar enhancement factor):
Reaction rate NA<σv> given in 105 cm3/mole/s, including SEF
