电子离化氢原子基态三重微分散射截面的研究

Research on Triple Differential Cross Sections for Ground State of Hydrogen Atom Ionized by Electrons

在共面非对称几何条件下,解出氢原子(e-2e)反应中基态的三重微分散射截面的解析表达式,分析了散射截面大小与入射能量的关系及有效电荷对binary peak和recoil peak的影响,其结论与实验结果相吻合.

The analytic expression of triple differential cross sections for ground state of （e-2e） reaction for hydrogen atom were computed in the case of asymmetric coplanar geometry. The effect on binary peak and recoil peak by effective charge was discussed and the relationship between differential cross sections and incident energies was obtained. The result was in good agreement with experimental measurement.
