通过测量从共面到垂直面几何形状的宽散射角范围内的（e，2 e）角关联，研究了氦原子在电离阈值以上3 - 10 eV能量范围内的电子碰撞电离。在这些测量中，两个出射电子以对称的散射角和相等的能量被观察到。
Electron-impact ionization of helium has been studied in the energy range from 3 - 10 eV above the ionization threshold by measuring (e, 2e) angular correlations over a wide range of scattering angles from the coplanar to the perpendicular plane geometry. In these measurements the two outgoing electrons are observed at symmetric scattering angles and with equal energies.
