给出了氦在与入射电子轨迹正交的垂直平面上（e, 2e）的符合测量结果。入射能量在电离阈值以上的10至80 eV范围内变化，结果既适用于对称能量共享，其中出射电子具有相同的能量，也适用于非对称共享。用于收集这些结果的实验装置是一台完全由计算机控制和计算机优化的光谱仪，能够访问从垂直到共面几何形状的广泛几何形状。
Results are presented of (e, 2e) coincidence measurements on helium in the perpendicular plane, defined as the plane orthogonal to the incident electron trajectory. The incident energy is varied in the range from 10 to 80 eV above the ionization threshold and results are presented for both symmetric energy sharing, where the outgoing electrons have the same energy, and for non-symmetric sharing. The experimental apparatus used to collect these results is a fully computer controlled and computer optimized spectrometer able to access a wide range of geometries from the perpendicular to the coplanar geometry.
