Formation of radiation defects in single crystals of NaCl and kcl irradiated with channeled electrons with energies 10‐50 keV

We present the results of investigations of the process of formation of F-centers in single crystals of NaCl and kCl upon exposure to 10–50 keV electrons with the incident electron beam directed at various angles to the crystallographic axes < 100> of single crystals. We showed that when the electrons are channeled, the rate of formation of F-centers increases, and the concentration of F-centers near the surface of the single crystals increases. We established a connection between the observed orientation phenomena in the formation of F-centers and the radiation dose and initial energy of the electrons. We determined characteristic angles for channeling the electrons.
