Abstract：
A new model, based on unified Hauser-Feshbach and exciton model, for neutron induced light nucleus reaction has been developed. In case of E n≤20MeV, the total cross section, non-elastic cross section, elastic angular distribution, and the energy-angular spectra of outgoing neutrons in n+¹¹B reaction have been calculated. Especially the double-differential cross section of outgoing neutrons particles of the ¹¹B(n,xn) reaction are calculation. Because of strong recoil effect in light nucleus reactions, the energy balance is strictly takeninto account. In case of ¹¹B, it has more reaction channels and complex reaction mechanism, and the two-body separations are also included in the calculation. This new model describes these characters of ¹¹B very well. From the comparison between calculated results and experimental data, one can see that this model works well in calculation both for cross section and for energy-angular distributions of outgoing neutrons.
