A study was made of the diffusion of D and H by making Gorsky-effect measurements. It was found that the diffusivity of H, at temperatures of between -60 and 200C, could be described by:

D (cm2/s) = 2.5 x 10-3 exp[-0.226(eV)/kT]

The diffusivity of D, within the same temperature range, could be described by:

D (cm2/s) = 1.7 x 10-3 exp[-0.206(eV)/kT]
