X-ray creation and activation of electron spin resonance in vitreous silica.

We report strong dependencies of electron-spin-resonance (ESR) signals in fused silica on x-ray dose, sample hydroxyl concentration [OH], and preirradiation sample-annealing temperature TF. In general, the strengths of the E'-center ESR signal and the two oxgyen-hole-center signals increase nonlinearly with Cu-target x-ray dose; we ascribe this behavior to the coexistence of two processes: (1) The x-ray activation of the spins of pre-existing structural defects, and (2) the x-ray creation af new similar defects
