摘　　要：在非共面非对称实验几何条件下,将C6+单离化基态H原子碰撞体系放入弱激光场下,理论推导体系的无修正和有修正的跃迁矩阵元,同时计算无激光场时体系的跃迁矩阵元,分别计算相应的三重微分散射截面,并用计算机数值模拟相应三维图像,观测分析弱激光场的存在对TDCS的影响.Under asymmetrical non-coplanar experimental geometry condition, we calculate the transition matrix element and corresponding triple differential scattering differential cross section when the scattering system of C6^＋ ion and ground state H atom in weak laser fields. We use 3D images analysis the effect of weak laser field to the triple differ- ential scattering section.
