氦原子(e,2e)反应中库仑波描述入射电子的理论研究
A theoretical study on the Coulomb wave describing the incident electron for (e,2e) processes on Helium
摘要
在前期工作的基础上,当初通道使用具有有效电荷库仑波时,完成了电子入射离化氦原子三重微分截面的理论推导.计算表明:初通道库仑场对较低入射能量情况下,(e,2e)过程的三重微分截面有较大影响.
Abstract
Based on our earlier paper, the triple differential cross section for electron impact ionization atomic helium are calculated by use of Coulomb waves with an effective charge for the initial channel wave function. It is shown that the initial channel Coulomb field play a major role in determining the triple differential cross section at near-threshold incident energy.
