Energy loss of charged particles in collision with atoms and surfaces

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

The interaction of charged particles with materials can always be associated with the energy transfer process that results in the change of the energy of the particles. In this chapter we show examples when projectiles suffer energy loss either in ion-atom, or electron-surface and ion-surface collisions. We present classical trajectory Monte Carlo results to calculate energy losses of the projectiles in proton-hydrogen atom collisions. The obtained results verify that high order effects should be included for a proper description of electronic stopping power. Energy loss of charged particles near surfaces pose several interesting problems, among them the separation of surface from bulk effects. We analyze the possible way of the separation in electron-surface and ion-capillary collisions. We show that the correlation between the angular distribution and the energy loss of ions passing through capillaries can be used to probe the surface loss functions without the contribution of the bulk one.
