摘要: 用经典轨道蒙托卡罗(CTMC)方法计算离子与氢原子碰撞过程电荷转移截面,并计算俘获电子的n(n为主量子数)壳层分布。对于多电荷离子的碰撞过程,利用约化变量得到了截面的q标度规律。计算结果与实验测量符合得很好。

Abstract: The classical trajectroy Monte Carlo method is empolyed to calculate the charge transfer cross sections and the n shell distribution of capture electron for the collision of ions with hydrogen.For the collision of partial ionized ions with hydrogen,a q-scaled cross section is obtained by introducing the reduced variables.The present results are in good agreement with experimentally measured results.

Key words: ion collision, classical trajectroy, charge transfer
