本工作是应用作者过去提出的表面耦合衍射几率方法来研究弯曲嵌镶晶体中子反射率随晶体摇动角变化的报道。作者分析了A.Boeuf等人所做的弯曲铜单晶的中子衍射实验,对应于三种不同波长及弯晶曲率进行了理论计算。与A.Boeuf等人的方法相比,本工作的计算结果与实验结果符合的程度有很大的改进。由于本方法是基于将晶体分成多层并考虑层与层之间入射与衍射中子束的耦合效应,因此它可以用来研究实验中 This work is to study the neutron reflectivity of bent mosaic crystal with the variation of crystal rocking angle by applying the method of surface-coupled diffraction probability proposed by the author in the past. The author analyzes the neutron diffraction experiment of the bent copper single crystal made by A. Boeuf et al., And theoretically calculates the three different wavelengths and curvatures. Compared with the method of A. Boeuf et al., The calculation results of this work are greatly improved in accordance with the experimental results. Since this method is based on the separation of crystals into multiple layers and considering the coupling effect between incident and diffracted neutron beams between layers, it can be used to investigate
