摘　　要：在共面非对称几何条件下,将能壳上跃迁矩阵元表示为结构因子和末态道两粒子间关联因子的乘积,推导出C6+离化He原子在不同动量转移下三重微分散射截面解析表达式,分析了实参数和有效电荷对散射截面角分布的影响.Under the Ehrhardt geometrical condition,in the process of calculating,the transition matrix element can be analytically expressed to be a product of two factors： the structure-scattering factor and the correlation factor of two particles in the final channel.We compute the triple differential cross section for the single ionization of helium by C ^6＋ ions under different momentum transfers.Regulate the value of the effective charge and parameter can make the theoretical curves are better agreement with experiment data in the two peaks.
