The diffusion kinetic of classic impurity particles has been investigated in the framework of the one-dimensional two-level model and applied for the explanation of solid hydrogen thermal conductivity data with extremely low concentrations of neon impurity in samples grown at different crystallization rates, at which the plateau effect was observed. The main idea is that heavy isotopic impurities could segregate into thin long chains near dislocation cores if the growth rate is slow. Neon impurity chains can persist for a long time. Such rigid linear objects ensure inelastic scattering of phonons. The diffusion coefficient of neon atoms in (p-H2)1−cNec mixtures was estimated for the experimental conditions with c = 0.0001 at. % and c = 0.0002 at. %.
