Аннотация:The structure of polycrystalline CeNi3Н3.0 hydride samples at 5 and 293 K has been studied byneutron diffraction. The hydrides have a rhombic lattice (sp. gr. Pmcn, no. 62, Z = 12). The site parametersof metal and hydrogen atoms have been determined. It is established that the distribution of hydrogen atomsover the hydride structure sites at 5 K is similar to the hydrogen distribution at room temperature. A comparisonof the neutron diffraction patterns obtained at different temperatures indicates a change in the samplemicrostructure upon cooling.
