Description
The coherent scattering length (b_c) is a key parameter for neutron experiments. In addition, the b_c for some nuclei have important physical significance. The b_c is measured by several methods, including cross-section measurements and diffraction, and is mainly measured using a neutron interferometer(NI). However, the sensitivity of conventional NI, which is made of Si crystal, has been limited by its experimental setup. Therefore, we developed a multilayer NI. Utilizing the multilayer NI with the pulsed neutron source supplied by J-PARC and the time-of-flight method, we can simultaneously use a wide range of neutron wavelengths. We observed an interferogram along wavelengths with higher sensitivity than conventional NI. In this presentation, we will report the latest results of the b_c measurements.
