Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
New rec. value is from recent evaluations (endfb71,jendl40) which fits data of Mac83a and NBL04, NBB06. However, there is an indication in NBL04 and NBB06 that the cross section towards higher energies (beyond 40 keV) is about 10% lower than given in the evaluations. More investigation needed. Uncertainties are from covariance data of endfb71 plus deviation of both evaluations.
Last review: July 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: endfb71,jendl40 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: 2013 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: Iodine
