Dynamic damping of dislocations in the irradiated LiF crystals
To study the nature of the mechanisms that limit the viscous motion of dislocations, the dampfed dislocation resonance in LiF crystals at room temperature in the range of radiation doses of 0-1000 R has been scrutinized by the impulse echo method in the frequency range 37.5-232.5 MHz. From the frequ...
