| Abstract: | Penetration of energetic charged particles through thick crystalline targets is reviewed. The theory of multiple scattering and energy loss is modified to include channeling effects. The relaxation of the flux distribution over the transverse plane which affects all interactions with atoms and nuclei in channeling is discussed in detail. A new type of energy loss due to spontaneous radiation of channeling particles in the continuum potential field is considered. |
