It was found that the data for 110Ag diffusion, into the cold end of a 5N-purity single crystal which was subjected to a temperature gradient, were described by:

D (cm2/s) = 2.1 x 10-1 exp[-39.5(kcal/mol)/RT]

N.Q.Lam, S.J.Rothman, H.Mehrer, L.J.Nowicki: Physica Status Solidi, 1973, 57[1], 225-36

The best linear fits to the solute diffusion data ([473] to [487], [517] to [528]) yield:

Ag: Ln[Do] = 0.33E – 15.5 (R2 = 0.73); O: Ln[Do] = 0.69E – 13.2 (R2 = 0.998);

O(l): Ln[Do] = 0.42E – 9.4 (R2 = 0.98)
