Available isotopes for Strontium (Z=38)

Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
New rec. value is weighted average of Koe00 and KZB90 (normalized by 632/586= 1.0785) and Mac89. Used normalized energy dependence and uncertainties of Koe00. Note that the values from the evaluated libraries are 20% lower than the recommended value. There is also a discrepancy between the latest TOF value of Koe00 and the activation value from KZB90. More investigation needed.
Last review: December 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: Koe00,KZB90,Mac89 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: 2015 X-factor: Reference: Year: SEF (Stellar enhancement factor): Reference: Year: Comment: Rate: Reaction rate NA<σv> given in 105 cm3/mole/s, including SEF Chart of nuclei
Isotope: Strontium
