介绍了一种改变和跟踪中子束非平行于磁场的极化的简单方法。这使得建立一种新的聚焦效应成为可能，我们称之为中子自旋回波。开发和实验测试的技术可以应用于几种新的方式，例如优越特性的中子自旋鳍，用于直接测定散射函数傅里叶变换的非常高分辨率光谱仪，用于广义极化分析，以及用于测量中子粒子性质的精度显着提高。
A simple method to change and keep track of neutron beam polarization non-parallel to the magnetic field is described. It makes possible the establishment of a new focusing effect we call neutron spin echo. The technique developed and tested experimentally can be applied in several novel ways, e. g. for neutron spin flipper of superior characteristics, for a very high resolution spectrometer for direct determination of the Fourier transform of the scattering function, for generalised polarization analysis and for the measurement of neutron particle properties with significantly improved precision.
