Available isotopes for Osmium (Z=76)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
Cross sections do not include stellar enhancement factors!
(Version 0.0 corresponds to Bao et al.)
Last review: July 9th, 2009
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
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.)
SEF (Stellar enhancement factor):
Reaction rate NA<σv> given in 107 cm3/mole/s, including SEF
