A theoretical approach was presented for the treatment of self-organization in irradiated crystals which contained traps for vacancies and interstitials. It was found that, in the system which was considered, 2 types of dissipative structure could arise. Temporal structures developed due to the release of energy during defect recombination, and absorption by sinks. The energy release resulted in crystal healing, followed by an augmentation of defect diffusion. The temporal effects involved oscillation of the defect density and crystal temperature, at frequencies which ranged from 10-5 to 0.1/s. Periodic defect density superstructures arose because of interactions, between defects, at defect production rates which were higher that a threshold level. The period of such superlattices ranged from 1 to 100nm, under normal irradiation conditions.
