Abstract
We discuss specific examples of desorption due to electron or photon bombardment of solids, in which the repulsive interactions that result in particle expulsion can be clearly identified. A particularly interesting example is the desorption of positive ions from alkali-halides. Classical trajectory calculations are used to provide a picture of the atomic-scale motion during desorption. The results show that dynamic distortions of the lattice play a crucial role in the desorption process.
