为了提高中子白束非弹性散射的测量效率，本文提出了一种中子白束非弹性散射的测量方法。该方法包括矩阵求逆和选择性提取。前者是解决每个入射能量分量的白光束数据，和后者消除污染的弹性组件，产生强烈的背景，否则混淆的非弹性散射分量。在这种方法中，获得高效率的最佳实验条件将在很大程度上取决于各个实验的具体目标。
We describe a method of white-beam inelastic neutron scattering for improved measurement efficiency. The method consists of matrix inversion and selective extraction. The former is to resolve each incident energy component from the white-beam data, and the latter eliminates contamination by elastic components, which produce strong backgrounds that otherwise obfuscate the inelastic scattering components. In this method, the optimal experimental condition to obtain high efficiency will strongly depend on the specific aim of the individual experiments.
