(Version 0.0 corresponds to Bao et al.) Comment
New rec. value is from TENDL-2015 (perfect agreement with MAB77b) using the uncertainty quoted in MAB77b. Note that there is a discrepancy between the evaluations (TENDL-2015 and ENDF/B, JEFF, JENDL), mainly due to the use of different thermal values and widths of the first s-wave resonance at 1.5 keV.
Last review: May 2016 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: MAB77b,tendl2015 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: 2016 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: Calcium
