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.
