That is, if EB is the vacancy-solute

proportionality constant A includes vibrational entropy effects. One can use Eq. (

42) in two physically meaningful ways. 80 I. P. STARK.

... 2a2 v exp (AS/k) exp ( - (A//v - £B + AHJ/kT)fT (44) EB is the solute vacancy

**binding energy**; one may compare Eqs. (19) and (44) where both give log Dproportional to 1/T only if fT is constant. Evaluation of fT is somewhat complex

In Table II, E is the solute pair

attraction energy. To compute the solute diffusion coefficient, one needs to

determine the correlation factor. The correlation factor was also calculated by

Stark (1973) ...
