一个完整的描述电子碰撞双电离需要确定的动量散射弹和两个弹出的电子。该实验被称为（e，3e），意味着一个入射电子产生三个电子的碰撞，这些电子被同时检测到。对于给定的入射电子能量和双电荷离子的指定的最终状态，横截面是八倍微分，并且通常被报告为三个出射电子的检测器的立体接收角和这些检测器中的两个的能量带通的函数（第三电子的能量通过能量守恒被固定）。
A complete description of electron-impact double ionization requires the determination of the momenta of the scattered projectile and two ejected electrons. The experiment is referred to as (e,3e) implying a collision in which an incident electron gives rise to three electrons that are detected in coincidence. The cross section for a given incident-electron energy and a specified final state of the doubly-charge ion is eightfold differential and is typically reported as a function of the solid angle of acceptance of the detectors of the three outgoing electrons and the energy bandpass of two of these detectors (the energy of the third electron being fixed by conservation of energy).
