Summary

By measurements of the diffusive flow velocity, data on the self-diffusion coefficient in hcp helium 4 crystals in the molar volumes 20.30-20.82 cm3/mole have been obtained. It is shown that the experimental data on self-diffusion in the temperature range 1.3-1.7 K are well described on the basis of the quantum mobility of thermal vacancies.
