Self-diffusion in the model metal was studied using molecular static and molecular dynamics techniques. The structure of defect-lattice configurations was obtained using the former technique. Using the latter technique, the vacancy diffusion mechanism was analyzed over a wide temperature range. Particular attention was paid to multiple jumps in the high-temperature region. The possible contribution of divacancies, within the limits imposed by the interatomic potentials used, was also considered.
