| Research Abstract |
Atomic resolution holography with neutrons offers 3D nucleus images around specific nuclei. This method will explore a new stage of local structure analysis, such as environmental structure around hydrogen or local magnetic structure, which cannot be obtained by other methods. As a fundamental study toward neutron scattering holography, we have measured neutron hologram of PdH single crystal. The resulted nucleus images of Pd and H exhibit minus and plus amplitudes, respectively, reflecting sign of the scattering lengths of Pd and H.
