Equilibrium molecular configurations around a ½[10¯1](111) edge dislocation in the face-centered cubic crystals were calculated by using molecular dynamics and the Girifalco potential. The dislocation was found to dissociate into 2 Shockley partials. The core of the partial dislocation was wider than that of the screw dislocation and its width was 17.5 times that of the Burgers vector. The compressive stress at the core reached a maximum value of 0.74GPa.
