Saturation studies of the electron spin resonance due to trapped electrons in gamma-irradiated and photo-ionized organic glasses

摘要: Relaxation times for trapped electrons in organic glasses at 77°K have been determined from the power saturation characteristics of electron spin resonance. The spin-lattice relaxation time T1 is longer than 10–3 sec, and spin-spin T2 decreases with γ-irradiation dose. behaviour a photo-ionized glass similar to that corresponding γ-irradiated when comparison made nearly same bulk concentration electrons.
