摘　　要：考虑末态波函数动量相关效应,计算了入射能量为5599 eV时,敲出电子等能分享几何安排下的He(e,3e)反应的五重微分截面,并比较采用各种末态波函数动量相关下的计算结果.表明理论计算结果在误差范围内与实验数据基本吻合,末态波函数动量相关效应对He(e,3e)反应的五重微分截面具有一定影响.The fivefold differential cross section for double-ionization of helium in the 5599eV incident energy are calculated through considering electrons momentum correlation effect of the final state function. These calculations are compared with the available experimental data. It is shown that the present results which take the momentum correlation effect of the final-state into account are agreement with experimental data. And also results indicate the momentum correlation effect of the final-state influence on the fivefold differential cross section for double-ionization of helium.
