Abstract
We have developed a microscopic model to study emission of fast electr ons in glancing-angle ion-surface collisions using a classical traject ory Monte Carlo approach. Our model accounts for dynamic image interac tions and multiple scattering near the surface. We show that a sizeabl e fraction of Che convoy peak is produced by ionization of electrons t ransiently bound to the impinging ion. Properties of the collision ker nels near the surface are discussed. Good agreement is found with our recent coincidence experiments for 0.2-0.5 MeV/u Li ions interacting w ith SnTe(001) surfaces.
