We performed molecular statics calculations of energy barriers for adatom moves in the vicinity of steps on Pt(1 1 1) surface. We used the semi-empirical many-body Rosato-Guillope-Legrand potential and we systematically calculated barriers for descent of straight steps, steps with a kink and small i
