Self-interstitial configurations were simulated by using an embedded-atom method interatomic potential, and a new embedded-defect model. The latter potential included angular-dependent many-body local terms. Formation energies and lattice distortions were calculated for the <110>- and <111>-oriented dumb-bells.
