Note (General): For the purpose to evaluate atomic diffusive dynamics in liquid Sn the inelastic neutron scattering measurement has been carried out. The quasielastic neutron scattering in a part of the inelastic scattering results from the diffusion or structure relaxational motion. The obtained width of the quasielastic line versus momentum transfer Q deviates from Fick's law and close to the jump-diffusion model corresponding to water. As Sn is the almost coherent scatterer, this width is considered to be derived from the existence of the correlated motion of particles. The quasielastic line behavior in liquid Sn may represent the slow structural relaxation of the particle shell around the new site after the jump motion of a Sn atom in diffusion process.
