Popis:	The thermal conductivity of solid hydrogen with 1–2ppm Ne impurity is investigated in the temperature range 1.5–10K on samples grown from the liquid phase at various growth rates. The results differ qualitatively from those obtained on samples grown from the gas phase: the thermal conductivity curve exhibited a dip in a broad plateau. A relaxation model is proposed to explain the effect, which is presumed to be due to linear impurity structures arranged on dislocation lines. A comparison with the case of isolated neon atoms homogeneously distributed in the solid hydrogen is made.
