| Abstract: | The system of kinetic equations for distribution functions of impurity excitations in solid 3He–4He mixtures in the presence of phonons is solved. The results obtained allows us to calculate the spin diffusion coefficient of3He–4He quantum crystals. The found expression differs from the results of the previous theoretical studies. A comparison of the obtained diffusion coefficient with experimental data makes it possible to determine the numerical values of the energy band width of impurity excitations. |
