摘要

在考虑初始和最终通道畸变影响的畸变波形式下，计算了氦基态单次电离的总截面(TCS)和单微分截面(SDCS)。目前的TCS和SDCS结果与实测值和其他理论预测的入射电子能量E i > 150 eV基本一致。

Total and Single Differential Cross Sections for the Electron Impact Ionization of the Ground State of Helium

Total cross sections (TCS) and single differential cross sections (SDCS) have been computed for the single ionization of the ground state of helium by electron impact in a distorted wave formalism which takes into account the effects of the initial and final channel distortions. The present TCS and SDCS results are in fair agreement with the measured values and other theoretical predictions for the incident electron energy E i > 150 eV.
