在入射电子能量为35.4 eV时，对电子碰撞电离氢分子产生的三重微分截面进行了全面的理论和实验研究，研究了出射电子能量相等和不等的情况，以及一系列实验几何结构。一般来说，良好的协议之间的理论方法和实验，最好的协议产生的中间几何形状与大枪角和垂直的几何形状。
A comprehensive theoretical and experimental investigation of the triple differential cross sections arising from the electron-impact ionization of molecular hydrogen is made, at an incident electron energy of 35.4 eV, for cases where the outgoing electrons have equal and unequal energies, and for a range of experimental geometries. Generally, good agreement is found between two theoretical approaches and experiment, with the best agreement arising for intermediate geometries with large gun angles and for the perpendicular geometry.
