Electron paramagnetic resonance (EPR) of defects in neutron-irradiated natural α-quartz exposed to doses from 1016 to 
has been studied. New E′ centers and other defects have been revealed. The intensities of hole-like defects, including a novel triplet-state 
center, and E′-type centers in relation to neutron fluencies and post-irradiation annealing temperature have been investigated. For the new 
center the primary spin Hamiltonian parameter matrices g and A (29Si) (hyperfine interaction for 29Si) as well as the radiation dose dependence and thermal stability have been determined.
