Abstract
Ba 2+ -doped LiF crystals were studied using the «dielectric loss» and «ionic conductivity» methods. By the first method we have indicated the existence of two relaxation mechanisms. The first mechanism is attributed to reorientation of ion-vacancy dipoles by means of nearest-neighbor to nearest-neighbor jumps. The estimated activation enthalpy h m and the preexponential factor τ 0 are 0.43 eV and 3.30×10 -9 sec, respectively
