An accurate determination of the self-diffusion coefficient in germanium has been obtained. In the temperature range 766-928^∘{}C, it is represented by D=7.8exp(-68500/RT) cm² sec. The probable errors in the frequency factor and activation energy are ±{}3.4 cm²/sec and ±{}0.96 kcal/mol, respectively.
