摘要
这篇文章,通过考虑末通道He^+中剩余电子的屏蔽效应,用BBK模型及修正方案在大能量损失小动量转移几何条件下对电子电离氯原子的三重微分截面进行了计算,并从物理本质上系统地研究和分析了剩余电子的屏蔽效应在大能量损失几何条件下对三重微分截面所产生的影响.
In this work,the triple differential cross section for electron impact ionization of helium in the special geometry of coplanar high incident energies large energy loss and close to minimum momentum transfer are calculated by use of the BBK and modified Bt3K model after the shield effect of the residual electron is considered. Then, the influences of the effective shield of residual electron on the triple differential cross sections and the physical nature of these effects are discussed in detail.
