Total Neutron Cross Section of Carbon from 1 keV to 15 MeV

Abstract
The total neutron cross section of carbon was measured over the energy range 1 keV to 15 MeV, using the U.S. National Bureau of Standards electron linear accelerator as a pulsed neutron source. Neutrom energies were measured by the time-of-flight method.The measurement accuracy is estimated to be ±¾% below 100 keV and ±1% above .The carbon cross section was fit with a polynomial from 0.001 to 1.4 MeV with the following coefficients σ = 4.757 − 3.419E + 1.548E2 − 0.328E3, where σ is in barns and E in MeV. Data are compared with other results.
