Channeling of fast particles in fullerites

A theory of channeling of relativistic electrons and positrons as well as positively and negatively charged ions in molecular crystals of fullerenes (fullerites) is developed. The crystal potentials are calculated, and the spatial and angular distributions of beams of particles propagating along principal crystallographic directions are determined. A method is developed for taking into account the effect of incoherent scattering on the channeling process.
