Diffusion coefficients for vacancies and self-interstitial atoms in vanadium at several temperatures were calculated by the molecular dynamics method using the Foiles-Adams potential. Apart from the migration energy, the pre-exponential factor was an object of interest. Simulation results showed that the self-interstitial atoms in vanadium existed in a <111> dumb-bell configuration and migrated exceptionally along <111> directions.
