Abstract Measurements of self-diffusion in bcc 3 He 24,20-24,80 cm 3/mole were carried out by a new method in the temperature range 0.4 - 0.8 K. The vacancy diffusion coefficient was obtained by comparison of the self-diffusion data and the vacancy specific heat. It is found out that the vacancy diffusion is independent of temperature, because of spin disorder in this region. The data obtained shows that vacancies in bcc 3 He are wide-gap quasiparticles.
