摘要
在考虑了He原子(e,2e)过程中,剩余电子对核的有效屏蔽之后,用修正后的BBK理论计算了入射能为40eV时,共面不对称几何条件下电子入射离化He原子的三重微分截面(TDCS).结果表明:该文得到的理论曲线更接近实验数据.
In this works, the triple differential cross sections for electron impact ionization of atomic at incident energies of 40eV in asymmetric geometry are calculated by use of the modified BBK model after the shield effect of the residual electron is considered for the (e, 2e) processes on helium. It has been found that the present results give a better description for the experimental data.
