Abstract

The Li diffusion in Li2S at high temperatures was investigated by quasielastic neutron scattering techniques on a single crystal of 7Li2S. It is shown by using polarized neutrons that the scattering is almost purely incoherent. The data were analysed in terms of an extended Chudley-Elliott jump diffusion model. The Li diffusion process takes place by hopping between regular tetrahedral and interstitial octahedral sites. The mean residence times on the regular Li sites were estimated to be 17.3 ps at T=1173 K, 6.7 ps at 1273 K and 4.3 ps at 1363 K.
