摘　　要：计算了敲出电子等能分享几何安排下,入射能量分别为5 599 eV和1 099 eV时He(e,3e)反应五重微分截面,并比较在He(e,3e)过程中散射粒子的相互作用和它们之间的干涉效应对五重微分截面的贡献.结果表明,理论计算数据在误差范围内与实验数据基本吻合,并且散射粒子的相互作用以及干涉效应对五重微分截面的影响都是不容忽视的.The He（e,3e） fivefold differential cross-section under the equal-energy share of knocked electron geometry arrangement is calculated, in which the incident energies are 5599 eV and 1099 eV, respectively. The contributions of different interactions as well as their interference effect in the He（e, 3e） process make to fivefold differential cross-section are compared. The result indicates that the theoretical calculation is in agreement with the experimental data in the error range, and each kind of interaction as well as the interference effect to fivefold differential cross-section＇ s influence should be not neglected.
