NIGMATULLINA This paper presents the results of studies by the method of inelastic neutron scattering of copper and silver chalcogenides at a temperature of 300 K in the non-superionic phase. Dynamic structural factors and generalized densities of the phonon states of these compounds were obtained. Inelastic peaks observed at 3…4 MeV energies presumably correspond to acoustic vibrations of phonons. The phonon spectra of copper and silver chalcogenides have features characteristic of structurally disordered compounds. Key words: lattice dynamics, inelastic neutron scattering, copper and silver chalcogenides, phonon spectrum, superionic conductors. DOI: 10.25791/infizik.09.2019.837 Contacts: - Pp. 31-37.
