description The methods of positron annihilation, backscattering of channeled ions, and electrical measurements are used to study GaAs and Si crystals after irradiation by supercurrent electron and proton beams. The dependence of positron annihilation parameters and of minority carrier lifetimes on the intensity and ddse of the electron and proton irradiation is obtained. Experirncntal results of the defect radiation annealing in crystals are discussed. Profiles of radiation damage in GaAs crystals are obtained using measurements of annihilation photon angular distribution. [Russian Text Ignored].
