Abstract
A multistring potential with the continuum approximation is used to simulate channeling of charged particles in monatomic and diatomic lattices. Different quantities are calculated: the trajectories, the flux distribution of channeled particles, the close-encounter probability, and angular distribution. The close-encounter yield for foreign atoms present in the channel is also computed and application is made to the lattice location of these atoms in the lattice. Results are given for various crystal types and in particular for bcc, fcc, diamond, and zinc-blende structures. Comparison is made with other computer simulations and, when possible, with experimental results. It is shown that the gross features are in agreement. The discrepancies are discussed.Keywords
