The diffusive behavior of 64Cu was studied at 97 to 300C. The results could be described by:

D (cm2/s) = 3.7 x 10-4 exp[-0.67(eV)/kT]

H.H.Woodbury, M.Aven: Journal of Applied Physics, 1968, 39[12], 5485-8

The best linear fits to the solute diffusion data ([26] to [45]) yield:

Cu: Ln[Do] = 0.21E – 14.3 (R2 = 0.06); Hg: Ln[Do] = E – 38.8 (R2 = 0.98);

In: Ln[Do] = 0.40E – 16.9 (R2 = 0.91); Na: Ln[Do] = 0.67E – 18.1 (R2 = 0.99)
