Abstract:
The radiation defect formation has been studied in beryllium oxide crystals irradiated with reactor neutrons in a wide range of fluences (10(15)-10(20) cm(-2)). It has been found that at high dose irradiation the saturation and reduction of anion and cation vacancies (the simplest point radiation defects) occurs in contrast to another alkaline earth oxides where only saturation takes place. A reduction of the point radiation defects under high dose irradiation has been caused not only by achieving a dynamic balance between creation and annihilation of Frenkel pairs but also by aggregation of the defects created. The mechanism of defect aggregation is discussed for the simplest aggregate defect-P--center (double cation-anion vacancy trapping an electron). A new aggregate paramagnetic centers have been registered in high-dose neutron irradiated BeO crystals.
