Nuclear Cross Sections: Cd-nat
One-group (thermal + fast) neutron cross-sections for key nuclides used in reactor physics — absorption (sigma_a), fission (sigma_f), capture (sigma_c), scattering (sigma_s), and transport cross-sections in barns. Covers fissile/fertile actinides (U-233, U-235, U-238, Pu-239, Pu-241, Th-232), moderators (H2O, D2O, graphite, Be), structural materials (Fe, Cr, Ni, Zr, Al), and neutron poisons (B-10, Cd, Xe-135, Sm-149, Gd). Data from ENDF/B-VIII.0 and Lamarsh.
