A study of the holographic image of the atomic arrangement in a PdH 0.78 single crystal, recorded using spherical neutron waves generated by incoherent neutron-proton scattering was presented. It was found that the resolution was sufficient to show the positions of single atomic nuclei on their respective lattice sites, despite the delocalization of protons due to the weak bonding of hydrogen dissolved in Pd. The ways by which the problems in the reconstruction of atomic positions related to the highly unfavorable sample shape could be solved were discussed. The ability of the technique to offer possibilities for the investigation of various materials containing substantial amounts of hydrogen was also presented.
