Available isotopes for Nickel (Z=28)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
Cross sections do not include stellar enhancement factors!
(Version 0.0 corresponds to Bao et al.)
Version 0.2: Corrected some typing errors and included one more old measurement: WKR84a. Recommended cross section is weighted average of PPH93, WKR84a, and BeS75. Version 0.3: Note that there is a clear discrepancy between the TOF measurements and the recent activation measurement with accelerator mass spectrometry from RDF07. Further investigation needed!

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: PPH93, WKR84a, and BeS75; energy dep. from PPH93
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.)
SEF (Stellar enhancement factor):
Reaction rate NA<σv> given in 106 cm3/mole/s, including SEF
