- Аннотация: Atomically ordered PdAgHx and PdCuHx hydrides with x approximate to 0.9 were synthesized in an atmosphere of gaseous hydrogen at P = 3 GPa. Their metal lattices with primitive tetragonal cells were formed on the basis of fee lattices of the initial PdAg or PdCu disordered alloys due to the ordering of the Pd and Ag or Cu atoms into alternate layers perpendicular to the tetragonal c-axis. Rietveld refinement of the neutron diffraction pattern of the PdCuHapproximate to 0.9 measured at 80 K, showed the H atoms to occupy octahedral interstitials within the Pd layers. The inelastic neutron scattering study of PdCuHapproximate to 0.9 and PdAgHapproximate to 0.9 showed a large difference between the Pd-H, Cu-H and Ag-H interactions. Values of 93 and 116 meV were predicted for the local H vibrations in dilute Ag-H and Cu-H solid solutions.
