摘要：

TIME-MULTI, a time-introduced Monte Carlo estimation code for multiple neutron scattering events in a thick sample, was designed to extract accurate neutron-capture cross sections. In order to obtain the energy and time-of-flight spectra of a captured neutron, the neutron's history in the sample was simulated by a Monte Carlo method. The code was applied to the H-1(n, gamma)D reaction with different sample thicknesses and was shown to give the correct capture cross section independent of the thickness.
