Atomic-resolution neutron holography was carried out utilizing the powder diffrcatometer in JRR-3M reactor. Spherically emitted neutrons around a PdH0.78 single crystal produced by incoherent neutron-proton scattering, which formed a hologram, were efficiently collected using multi array 3He detectors. In addition to the hologram data, strong undulation due to the elastic thermal scattering was observed. To exclude this effect, the thermal scattering pattern was calculated and subtracted from the measured data. From the resulting hologram data, neighboring Pd and H nuclei images were successfully reconstructed.
