An electron impact double ionization experiment with complete determination of the electron kinematics of all three outgoing electrons measured in coincidence, will be developed and applied to investigations of collisions of electrons with alkaline earth atoms. The experiments will be carried out in an energy regime in which the plane wave impulse approximation can be used as the basis for comparison with experimental predictions. The experimental results will provide new understanding of electron-electron interactions (correlations) and their effects on orbital motion of electrons.

电子碰撞双电离实验将用于研究电子与碱土原子的碰撞，该实验将完全测定三个出射电子的电子运动学。实验将在一个能量范围内进行，其中平面波脉冲近似可以作为与实验预测相比较的基础。实验结果将提供对电子-电子相互作用(关联)及其对电子轨道运动的影响的新的理解。
