  Using previous experimental data of diffusion in metallic alloys, we obtain
real values for an interpolation parameter introduced in a mean-field theory
for diffusion with interaction. Values of order 1 were found as expected,
finding relevance for this quantity as a way to better understand the
underlying dynamics of diffusion processes. Furthermore, using this theory, we
are able to estimate the values of the mean-field potential from experimental
data. As a final test, we reobtain, with all this information as an input to
our simulations, the diffusion coefficient in the studied metallic alloys.
Therefore, the method provides appropriate transition probabilities to perform
Monte Carlo simulations that correctly describe the out of equilibrium
behavior.
