用连续离散耦合道方法（CDCC）系统地研究了入射能量高达150 MeV的Li原子与核子的散射。用赝态方法对Li的连续态进行了离散。CDCC方程中的对角势和耦合势是通过将复杂的Jeukenne-Lejeune-Mahaux有效核子-核子相互作用与相应的Li的束缚态和离散连续态之间的跃迁密度折叠得到的。确定了复有效相互作用的归一化因子，以便重现Li的中子和质子反应总截面福尔利实验数据。采用归一化因子的CDCC计算很好地再现了核子与Li的弹性和非弹性散射的实验微分截面。
Nucleon scattering fromLi is analyzed systematically over a wide range of incident energies up to 150 MeV with the continuum discretized coupled channels method (CDCC) capable of treating the breakup ofLi. The continuum states ofLi are discretized with the pseudostate method. Diagonal and coupling potentials in the CDCC equation are obtained by folding the complex Jeukenne-Lejeune-Mahaux effective nucleon-nucleon interaction with transition densities between corresponding bound and discretized continuum states ofLi. The normalization factors of the complex effective interaction are determined so as to reproduce experimental data on neutron total and proton reaction cross sections forLi. CDCC calculations with the normalization factors reproduce experimental differential cross sections for nucleon elastic and inelastic scattering fromLi well.
