脉冲中子源的最新进展使得中子衰减谱的能量分辨分析成为可能，其中包括中子散射的信息。在这项研究中，展示了一种新的小角中子散射（SANS）分析技术。不同纳米结构钢的中子衰减谱存在明显差异；这种差异可以理解为由 SANS 引起的衰减引起的。根据相应的 SANS 剖面计算出的中子衰减谱与实验观察到的衰减谱非常吻合。这一结果表明，中子衰减谱的测量可能有助于开发一种新的实验技术，即能量分辨 SANS。
Recent progress of pulsed neutron sources has enabled energy-resolved analysis of neutron attenuation spectra, which include information on neutron scattering. In this study, a new analysis technique for small-angle neutron scattering (SANS) is demonstrated. A clear difference is observed in the neutron attenuation spectra between steels with different nanostructures; this difference can be understood as arising from attenuation due to SANS. The neutron attenuation spectra calculated from the corresponding SANS profiles agree well with the experimentally observed attenuation spectra. This result indicates that measurement of neutron attenuation spectra may enable the development of a novel experimental technique, i.e. energy-resolved SANS.
