Abstract

The crystal structure of Ta₂D has been refined on the basis of neutron diffraction data taken by a high-resolution powder diffractometer HRP at the KENS pulsed neutron source. The diffraction pattern contains as much as 279 reflections covering a d-range of 0.05–0.28 nm. From the Rietveld analysis, a tantalum atom displacement induced by the ordered deuterium arrangement has been refined as 0.0059±0.0002 nm.
