An experimental investigations of the total neutron cross section for natural carbon were done at Kyiv Research Reactor using neutron filtered beams with energies 2, 3.5, 12, 24, 55, 59, 133 and 148 keV. The intense neutron beams formed by composite neutron filters at reactor horizontal channels had the fluxes of about 106-107 neutron/cm2.s at the fixed neutron energies and this enabled to measure the neutron cross sections with accuracy better than 1%. Transmission method was used in these measurements. The results are presented together with the analysis of the known previous experimental data and the evaluated nuclear data from ENDF libraries.
