摘要
采用二体碰撞近似和托马斯 -费米近似计算了多电荷离子18Arq+( q =3,4 )与中性原子H和He碰撞的电荷剥离截面以及Arq+的势函数和电子动量分布 ,计算结果与文献 [4]中的数据符合得较好。所导出的计算公式和编制的计算程序可以计算任何一个多电荷离子Aq +与H或He碰撞的电荷剥离截面。因而具有一定的普适性。
The charge stripping cross sections for 18 Ar q+ (q=3,4) by collision with neutral atoms H and He, potential functions and electron momentum distributions are calculated by using Binary Encounter and Thomas Fermi Approximations. Computational results agree better with data of reference[5]. Our caculation formulae and computational programme can calculate charge stripping cross sections for any other multicharge ions A q+ by collisions with H and He, so there is some general significance.
