| 摘 要： | 从跃迁矩阵元双势公式出发,给出了电子碰撞氢原子电离振幅的一个解析表达形式.计算中将散射电子波函数取为正交于氢原子的库仑波函数,不仅使跃迁矩阵元的第一项对三重微分截面（TDCS）贡献为零,而且减弱了TDCS中recoil峰的强度.最后将理论结果与实验结果进行了比较.

| Abstract: | An analytic expression for ionization amplitude of hydrogen by electron impact is provided within the frame- work of the two-potential formulaic. By using the orthogonalization of the Coulomb wave function to all occupied cribitals of the hydrogen atom for ejected electron, the contribution of the first term of the transition matrix element to triple differential cross sections （TDCS） is zero, and the intensity of recoil peak in TDCS has been decreased strongly. The present results are compared with experimental data. |
