The temperature dependence of the diffusion of 3He impurities in solid 4He and HD impurities in solid para-H 2 is calculated for the regime where coherent motion of the isotopic impurities is interrupted by scattering from vacancies or phonons. In both cases the best fit to the experimental data is
