† self-shielding not included
‡ at the end of irradiation
Notes & updates
- All capture cross sections are from then ENDF/B-VIII.0 library.
- Threshold reactions are from the TENDL-2019 nuclear data library
, which extends up to 200 MeV.
- Self-shielding is included for all samples. No multiple-scattering included, so far. Full attenuation infos are in this table >>
- Table in text form
Comments
Updated version, after correcting the self-absorption correction calculation technique. The previous version is available here. --
