The correlated diffusive motion of particles induced by a randomly migrating vacancy in the tetrahedral or octahedral interstitial sites in a bcc lattice, which each form non-Bravais lattice was studied within the encounter model using Monte Carlo simulation techniques. It was found that the tracer correlation factor for each case was in good agreement with the results obtained by Koiwa and Ishioka using the Green function approach
