The dependence of the sputtering yield K on the angle of incidence ϕ is calculated for single crystals by taking into account multiple collisions of the ions with atoms of the crystal. The secondary collisions increase the maxima of the curve K (ϕ) but do not alter the form of the minima. The effect of lattice defects on the function K (ϕ) is also considered. These defects mainly alter the minima in K (ϕ) and on the whole decrease the anisotropy of the sputtering yield. Electron emission from single crystals due to ion bombardment is treated in a similar way assuming a kinetic emission mechanism.
