Available isotopes for Tantalum (Z=73)
Recommended MACS30 (Maxwellian Averaged Cross Section @ 30keV)
180mTa 181Ta
Cross sections do not include stellar enhancement factors! History
(Version 0.0 corresponds to Bao et al.) Comment
Rec. value is from Wis04a. Note: this is the cross section from the stable isomeric state. Calculations include only captures from the short-lived ground-state (unless noted otherwise). Note that the stellar enhancement factor for isomeric states is quite uncertain.
Last review: In process 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:
