直到最近，人们才充分认识到交换相互作用在磁性晶体电子散射中的作用。在本文中，我们证明了库仑和交换散射势之间的干涉可以导致低能量弹性散射电子束的大极化。描述了一个可以测量这种效应的双散射实验。
The role played by the exchange interaction in the scattering of electrons from magnetic crystals has not been fully appreciated until recently. In this paper, we show that the interference between the Coulomb and the exchange scattering potentials can lead to large polarizations of a beam of elastically scattered low-energy electrons. A double-scattering experiment that can measure this effect is described.
