Recoil energy during ion motion in a crystal

Abstract

Computer calculations of the recoil energy during the motion of accelerated ions in a crystal with the bcc (body-centered cubic) lattice are carried out using the molecular dynamics method. The spatial distributions of the recoil energy in the target volume are obtained. Anisotropy of the energy distribution caused by the crystal structure of the target is observed. It is established that a high recoil energy is characteristic of close-packed atomic layers of the crystal that are perpendicular to its surface. The recoil energy maximum is related to the second atomic layer.
