On the energy distribution and angular distribution of sputtered particles

Abstract
The influence of the anisotropy of the momentum recoil density of collision cascades in solids on the energy and angular distribution of sputtered particles is considered. Various sputtering mechanisms are discussed. For some of those mechanisms this anisotropy leads to deviations from a ε−2 asymptotic form in the energy distribution and to an asymmetry in the angular distribution as a function of the angle of incidence of the projectile.
