Abstract. Energy-resolved neutron transmission imaging experiment was carried out to characterize the liquid phase of lead bismuth eutectic (LBE). The neutron transmission image confirmed that the LBE is homogeneous in a sample vessel. The obtained neutron transmission spectrum of the liquid LBE shows a wavy behavior in the wavelength dependence. This behavior is attributed to neutron attenuation by the neutron diffraction of the liquid LBE, which can give information about the atomic structure of the liquid LBE similar to Bragg edge transmission in the crystalline solid phases.
