Calculation of Double-Differential Cross Sections of n+7Li Reactions Below 20 MeV

Abstract

A new reaction model for light nuclei is proposed to analyze the measured data, especially for analysis of the double-differential cross sections of the outgoing particles. Many channels are opened in the n+7Li reaction below En 20 MeV. The reaction mechanism is very complex, beside the sequential emissions there are also three-body breakup processes. Because of a strong recoil effect of light nucleus reactions, the energy balance is strictly taken into account. The comparisons of the calculated results with the double-differential measurements indicate that the model calculations are successful for the total outgoing neutrons.
