H原子(e,2e)反应散射角对电子角分布的影响

在（e,2e）反应的过程中，利用双势公式^[3]，将散射振幅写成微扰矩阵的形式。在略去相对运动和质心运动的影响的条件下，在中能区Ei=150eV,Ef=3eV时，对于不同散射角，利用最佳截段思想，我们在入射道引进库仑波函数对其加以修正，理论上计算了共面非对称和上三重微分截面大小，结果表明理论分析方法是可行的。

Hydrogenous (e,2e) reaction influence of scattering angle toelectron angle

We transform scattering amplitude during the(e,2e)reaction into perturbation matrix by using two-potencial formula.In mid-energy Ei=150eV ,Ef=3eV region ,we calculate the triply-differential cross sections In coplanar asymmetric geometry theoretically, introducing a Coulomb wave function for revising it and using high point way in different scattering angle, without the consideration of the influence of relative and center of mass movement,The feasibility of the method was theoretical analsis.
