A study was made of the diffusion of 82Br. The diffusion coefficient in the low-temperature region was governed by diffusion along dislocations, and an increased dislocation density in the specimens resulted in much higher diffusivities. The diffusivity at 650 to 750C could be described by:

D (cm2/s) = 1.0 exp[-1.70(eV)/kT]
