摘要：

The structure of beta LaNi//5D//x was solved using neutron powder diffraction methods by making use of two specimens, one composed of normal Ni, the other of **6**0Ni. The diffraction patterns showed the existence of a superlattice line which could be indexed if the hexagonal unit cell of the metal was doubled along the C axis. The structure was refined by the method of Rietveld in space group P6//3mc with good agreement between the observed and calculated intensities. The deuterium was found to occupy three different sites: two tetrahedrally coordinated with Ni//4 and La//2Ni//2 neighbours and one octahedral site, La//2Ni//4.
