The thermal conductivity of CH4-Kr solid solutions is investigated at CH4 concentrations 0.2√5.0% in the temperature range 1.8√40 K. It is found that the temperature dependence of the thermal conductivity has features typical of resonance phonon scattering. The analysis of the experimental results shows that the main contribution to the impurity-caused scattering of phonons is made by the scattering on rotational excitations of the nuclear spin T-species of CH4 molecules. The phonon-rotation interaction parameter is estimated.
