ON HYDROGEN LOCALIZATION IN THE BETA' PHASE OF VO0.2

The results of an investigation of the dynamics of hydrogen atoms in t he body-centered tetragonal lattice of the interstitial beta' phase of vanadium-oxygen by the method of inelastic scattering of slow neutron s are reported. It is concluded on the basis of an analysis of the str ucture of the alloy investigated that hydrogen in the lattice is local ized in tetrahedral interstices with the point symmetry of an almost i deal tetrahedron.
