With the progress of pulsed neutron techniques, neutron transmission spectroscopy became able to provide the structural information in samples via the neutron attenuation by neutron scattering. This technique is known as the Bragg edge transmission analysis for crystalline materials. The Bragg edge transmission analysis is widely applied to neutron imaging experiments. In contrast, little attention has been paid to the neutron diffraction contributions from liquid and amorphous materials in the neutron transmission spectra. In this study, we measured and analyzed the neutron transmission spectra of liquid lead-bismuth eutectic (LBE) to clarify the relation between the neutron transmission spectra and diffraction profiles of liquid and amorphous materials.
