在统一的豪泽 -费许巴赫理论和激子模型的基础上 ,利用光学模型来处理中子诱发轻核核反应的一种新理论已经产生 .利用这一新理论 ,对当入射中子En≤ 2 0MeV时n + 11B反应的所有反应截面 ,出射中子和α粒子的双微分截面进行了计算 .通过比较理论计算的各种截面 ,出射中子总的双微分截面与实验数据 ,可以认为这一理论模型处理轻核核反应是很成功的 Based on the unified Hauser-Fischerbach theory and exciton model, a new theory of using optical model to deal with neutron-induced light nuclear reaction has been developed.Using this new theory, All reaction cross sections of n + 11B reaction at 2 0 MeV, double differential cross section of exiting neutron and α particle were calculated.According to the theoretical calculation of the total cross sections and experimental data of the various cross sections and exiting neutrons, it can be considered that A theoretical model for the treatment of the light nuclear reaction is very successful
