Investigations of diffusion processes in liquid lithium and lithium-hydrogen melt by quasielastic neutron scattering

The quasielastic neutron scattering experiments on liquid lithium (at 500 K and 830 K) and lithium-hydrogen melt (99 at.% Li7 and 1 at.% H at 830 K) were performed with the DIN-2PI time-of-flight spectrometer (FLNP, JINR, Dubna). The characteristics of the diffusion mobility for particles comprising...

Description
Summary:The quasielastic neutron scattering experiments on liquid lithium (at 500 K and 830 K) and lithium-hydrogen melt (99 at.% Li7 and 1 at.% H at 830 K) were performed with the DIN-2PI time-of-flight spectrometer (FLNP, JINR, Dubna). The characteristics of the diffusion mobility for particles comprising the liquids studied are extracted from the experimental results and analyzed with the help of the phenomenological and theoretical models. The self-diffusion coefficient in liquid lithium obtained for both temperatures is in the agreement with the one known in literature. The questions connected to hydrogen diffusion in the liquid lithium are discussed.
