Determining the probability of the neutron–antineutron transformation has been the subject of research for five decades. To increase the luminosity in experiments to measure the probability of this process, it is proposed that a neutron guide be used as it increases the solid angle of neutron-source visibility. To increase the range of values of the wave vector of neutrons and antineutrons, it is proposed that a neutron guide with a supermirror coating be employed. In this work, we simulate a multilayer structure in which the range of wave-vector values is extended. The structure is a supermirror in which the layers consist of tungsten and barium isotopes.

反中子超级镜

确定中子-反中子转变的概率是 5 年来的研究主题。为了增加实验中的光度以测量该过程的概率，建议使用中子引导器，因为它增加了中子源可见度的立体角。为了增加中子和反中子波矢量的取值范围，建议采用具有超镜涂层的中子波导。在这项工作中，我们模拟了一个多层结构，其中波矢量值的范围得到了扩展。该结构是一个超级镜子，其中的层由钨和钡同位素组成。
