  Diffusional interactions within the Ostwald Ripening process are analyzed in
the present paper. An {\it off-centre diffusion approach \/} is performed to
point out the direct correlation between the size of clusters. Herein the
diffusion solution is derived as a function of both the growing and shrinking
cluster sizes. Also, it is shown that the frequency transfer of particles
between the shrinking cluster and the growing one may acquire high values due
to the medium polarization. As a result, the temporal power law of the cluster
growth derived in this theoretical model differs from that predicted by the
{\it LSW \/} theory. Experimental data for $Ag$ clusters embedded in a $KCl$
matrix are analyzed both by the present theory and by the $LSW$ theory.
