Effect of dislocations on channeled relativistic electron motion

Motion of electrons with 21 MeV energy is studied by mathematic simulation method under their channeling along (111) axis of crystal, containing dislocations. A case is considered, when channeling direction is perpendicular to the dislocation line and Burgers vector. In this case the electron motion occurs in the field of bent atomic chains. It is shown that electron channeling is instable in relation to scattering on dislocations. 3 refs.; 2 figs
