The nature of the structural phase transition of quartz under neutron irradiation was studied by X-ray diffraction analysis. The kinetics of gamma luminescence (GL) bands in quartz crystals grown on seeds irradiated with neutrons with a dose of 5-1018..1019 and 5-1019 n/sm2 after additional neutron irradiation of 1016- 8.1020 n/sm2 in the temperature range 77-300 K. Based on experimental data, it is shown that all the structural characteristics of the seed are transferred to the grown crystal. This opens up the possibility of obtaining quartz crystals with predetermined properties. Diffraction parameters of quartz irradiated with neutrons and grown on neutron-irradiated seeds (n/sm2). Based on the results of studies of GL, the redistribution of the intensities of photoluminescence bands under illumination (λw = 300-340 nm) without heating and with heating in the temperature range 300-720 K, the dependence of the intensities of luminescence bands on the neutron fluence, it was assumed that the luminescence centers are at 550 and 660 nm are, respectively, peroxide radicals and non-bridging oxygen atoms located at the interfaces between the α- and β-phases of quartz.
