In this paper, we carried out atomistic calculations to investigate in detail the core structure and motion mechanism of the 1 2 < 1 1 1 > f1 1 2g edge dislocation in a-iron. First, molecular statics simulations are used to characterise the dislocation-core structure in the framework of the Peierls-
