Available isotopes for Lanthanum (Z=57)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)

Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
Rec. values are from RTe06 which uses ODH03 at kT= 25 keV for normalization and jendl33 for extension to higher energies. MACS at kT= 5 keV is weighted mean of values from WDH06b and RTe06.
Last review: Juli 2013 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: RTe07,jendl33,WDH06b,ODH03 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: 2007 X-factor: Reference: Year: SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 106 cm3/mole/s, including SEF Chart of nuclei
Isotope: Lanthanum
