Abstract A type Ia diamond crystal with a nitrogen impurity in different forms was 3.5 MeV electron-irradiated with successively increasing doses 5 × 1016, 2 × 1017, 4 × 1017, 2 × 1018 e/cm2 and examined after each dose by positron annihilation, EPR and optical spectroscopy in visible and IR regions. After irradiation with highest dose a development of the defective structure of the crystal was revealed. A detail description of the phenomenon, data of EPR and optical measurements for different irradiation doses are given. The first results of cathodoluminescence studies of the as-developed structure are presented. Possible models of defects responsible for main lines in CL spectra are listed.
