Measurements of Differential 14.7-MeV Neutron Scattering Cross Sections of Lithium-7 and Beryllium-9

The differential 14.7-MeV neutron scattering cross sections of ⁷Li and ⁹Be have been measured by means of a fast neutron time-of-flight spectrometer with a flight path of 1.5 m and a time resolution of 1 ns. The experimental data were analyzed in terms of an optical model for which a set of parameters was obtained. Good agreement of measured results with theoretical calculations and with the data given by Hogue et al. and Merchez et al. were obtained.
