730eV电子碰撞He原子(e,2e)电离的三重微分截面
Triple differential cross section for(e, 2e)ionization of helium by 730 eV electron
摘要
Abstract
Both initial-state correlation effect between electrons of helium, final-state correlation effect between ejected electron and remaining bound electron and final-state screening effect have been considered. The triple differential cross sections for ionization of helium by 730 eV electron are calculated and analyzed in the special geometry of coplanar, large energy loss and small momentum transfer. The present results are compared with the relative experimental data and CCC theoretical calculations from Stevenson et al. It was found that the present results give a better description for the structure of the triple differential cross sections from experimental data.关键词
