本文介绍了一种新的实验方法，它允许散射角的范围被扩展到覆盖整个后半球，即高达，在弹性电子散射的测量。这是通过在常规静电电子能谱仪的相互作用区域中添加局部磁场来实现的。本文测量了能量为10 eV的电子被氩原子弹性散射的微分截面，以及在固定散射角下的共振结构。
A new experimental method is described which allows the range of scattering angles to be extended to cover the whole of the backward hemisphere, i.e. up to , in measurements of elastic electron scattering. This is achieved by adding a localized magnetic field to the interaction region of a conventional electrostatic electron spectrometer. Measurements are presented of the differential cross section from 30 - for elastic scattering of electrons by argon at an energy of 10 eV, and of the resonance structures due to the states of at the fixed scattering angles of , and .
