The interaction of land 5 kev copper atom (primaries) impacting the Oil surface of copper crystals was studied using an "n-body type" computer simulation program. Each primary energy was studied using both the Bohr and Gibson II copper on copper potentials. Primary penetration and lateral drift or spread were investigated as a function of impact point. The n-body program has greater penetration values than the binary model used by Robinson and Oen¹³. Drift or spread (defined as wander if energy loss rate is low) occurs in the impact region of transition from hard interaction (near a lattice atom) to soft interaction (open or channel regions). Penetration and spread contours are presented.
