IAEA 2017 Neutron Data Standards in Table Format A. D. Carlson et al, Nuclear Data Sheets 148 (2018) 143-188. https://doi.org/10.1016/j.nds.2018.02.002 Table. natC(n,n) point-wise cross section data. It is a standard from 10 eV to 1.8 MeV. CS is the cross section. DCS is the cross section uncertainty. The 0.65 % unrecognized systematic uncertainty is included in the uncertainties in the table. Linear interpolation is recommended except below 30 keV where log-log interpolation should be used.
