Abstract

The possibility of channeling the low-energy (5-20 MeV) relativistic positrons around separate crystallographic axes with coaxial symmetry of negative ions in some types of crystals is shown. The process of annihilation of positrons with electrons of medium was studied in detail. The lifetime of a positron in the channeling regime was obtained to be 10-6 s that exceeded those for conventional cases in 109-108 times.
