| 摘 要： | 本文提出了程函近似下计算非弹散射跃迁矩阵元的非分法形式分析方法。引入实参数空间，使跃迁矩阵元中入时粒子坐标与靶原子坐标相分离，并将其表示为靶原子的形状因子与入射粒子扭曲因子乘积的积分形式，进而简化为二维数值积分。采用峰点近似，对电子和氢原子非弹散时的角分布作了数值计算，给出较好的结果。

| Abstract: | A formal analysis method for calculating the transition matrixelement of intiastic scattering in eikonal approximation is produced.By introducinga real parameter space,the coordinates of the projectile and that of the boundelectrons are treated separately,and the transition matrix element is expressed ina integral form, that is the target form factor multipliy by the projectile distortionfactor,it is them,reduced a two-dimension numerical integral,Using the peak-ing approximation we calculated the differential cross sections for the inelastic scattering of the electron and hydrogen. The results are better. |
