Abstract

The application of the method of phase-amplitude functions to the calculation of neutron-transmission processes in layered media containing highly absorbent elements is described. This method allows us to simultaneously calculate the reflection, transmission and absorption coefficients for neutrons. It requires less computing resources than other algorithms. A generalization of the method to matrix equations used in polarized neutron reflectometry is also presented. Examples of calculations of various characteristics of neutron transmission for layered resonator-type systems with a potential well are given.

摘要

描述了相位幅度函数方法在计算含有高吸收性元素的层状介质中的中子传输过程中的应用。这种方法使我们能够同时计算中子的反射、透射和吸收系数。与其他算法相比，它需要更少的计算资源。还介绍了该方法对偏振中子反射计中使用的矩阵方程的推广。给出了具有势阱的层状谐振器型系统的中子传输各种特性的计算示例。
