Abstract

The neutron-emission cross sections for an incident neutron energy of 14.8 MeV were measured at 90° for Be, B, C, Mg, Si, Ti, V, Mn, Fe, Co, Ni, Cu, Se, Y, Mo, Cd, Sb, Ce, W, and Pb by means of a neutron time-of-flight spectrometer. The experimental data were corrected for neutron multiple scattering. From the experimental inelastic neutron distributions, the distributions for the emission of the first and second neutrons, respectively, were calculated for the medium and heavy nuclei on the basis of the statistical-model treatment of Lang and Le Couteur. The corresponding nuclear temperatures for the emission of the first and second neutrons were also obtained. The calculated inelastic distributions for the emission of the first neutrons were used to obtain the level-density parameters based on the Fermi-gas model.
