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 >>
