Basics of Ion Scattering in Nanoscale Materials

subject

description

Energetic ions interact with materials by collisions with the nuclei and electrons of the atoms that make up the material. In these collisions, energy and momentum is transferred from the projectile particle, which is a moving atom or ion, to the target particles (atomic nucleus or electron). Each collision leads to a slowing down of the moving projectile and also a deflection of the trajectory that gives rise to the term scattering, which is often used synonymously to describe the energy transfer process.
