A study of quantum diffusion in solidH2 is reported based on the measurement of the pressure versus time at constant volume. Solid samples with ortho-He concentrations between 0.01 and O. 025 were investigated over the temperature range 0.4-4 K. The characteristic time constant 7 for ortho pair form

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
