Atomic Resolution Neutron Holography

Abstract

Neutron holography is a relatively new method, which can offer 3D nucleus images. We performed the neutron holography experiment for the first time in Japan. In the present article, theory, experimental setup and result of PdH_0.78 sample are introduced. The observed neutron intensity distribution around the sample includes thermal diffuse scattering rather than hologram data. A pure hologram was extracted by subtracting accurately calculated diffuse scattering pattern from the observed intensity distribution, and then, nucleus images around H were successfully reconstructed. In addition to this PdH_0.78 result, I discuss perspective of neutron holography with a topic of X-ray fluorescence holography.
