报道了中子偏振多层薄膜单色仪开发的最新进展。特别是，由双层厚度约为 50 A 的 Fe 和 Ge 薄膜组成的多层膜已制成具有高峰值反射和偏振效率。将多层反射率和偏振效率的测量结果与其他中子偏振器进行了比较。还获得了各个 Fe 和 Ge 薄膜的微观结构图片。最后，讨论了偏振多层膜的实际应用。
Recent progress in the development of polarizing multilayer thin-film monochromators for neutrons is reported. In particular, multilayers consisting of thin films of Fe and Ge with bilayer thicknesses of the order of 50 A have been made with high peak reflectives and polarizing efficiencies. The results of measurements of multibilayer reflectivity and polarizing efficiency are compared with other neutron polarizers. A picture of the microscopic structure of the individual Fe and Ge films has also been obtained. Finally, practical applications of polarizing multibilayers are discussed.
