Computer simulation of ion bombardment collision cascades

A Monte-Carlo code is described which simulates features of collision cascades due to ion bombardment. The effects of including an energy loss, U, from the recoiling atom during the displacement process is investigated for 0 ≤ U ≤ Ed . Depending on whether U = 0 or U = Ed is used, the fraction of replacement collisions is determined as 0.28 or 0.19 respectively. Also the fraction of energy expended in elastic collisions and displacement events, …
