Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
62Ni 63Ni




Cross sections do not include stellar enhancement factors!

(Version 0.0 corresponds to Bao et al.)
Comment
Previous recommended cross section was 12.5 (40) mb (due to subtraction of subthreshold resonance before extrapolation to stellar energies).
New recommended value is weighted average of recalculated value from NPA05 and values of SWa08, ABE08, and BeS75.

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:
cDirectly quoted from the reference itself
rRecalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
aCalculated from resonance parameters with the formula from Ref. 45
sSemiempirical estimates given in the reference
eEvaluated value taken directly from the reference

MACS:
Reference: BeS75,NPA05,ABE08,SWa08,jendl33
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.)
