Реферат: | eng: Electron paramagnetic resonance (EPR) of defects in neutron-irradiated natural alpha-quartz exposed to doses from 10(16) to 10(20) n/cm(2) has been studied. New E' centers and other defects have been revealed. The intensities of hole-like defects, including a novel triplet-state H-1 '' center, and E'-type centers in relation to neutron fluencies and post-irradiation annealing temperature have been investigated. For the new E-13' center the primary spin Hamiltonian parameter matrices g and A(Si-29) (hyperfine interaction for Si-29) as well as the radiation dose dependence and thermal stability have been determined.
