Abstract
Irradiation of LiNbO3, single crystals using Van de Graaff electrons with an energy of 1.5 MeV introduces an optical absorption band similar to that observed in thermochemically reduced samples. As-grown, reduced, or irradiated crystals show single-component positron lifetime spectra with an average decay time of 234 ps.
Die Bestrahlung von LiNbO3-Einkristallen mit 1,5 MeV-Van de Graaff-Elektronen verursacht eine optische Absorptionsbande, die ahnlich der in thermochemisch reduzierten Proben beobachteten Bande ist. Unbehandelte, reduzierend behandelte und bestrahlte Kristalle zeigen Positronen-Lebensdauerspektren mit einer einzigen Komponente mit dem Wert 234 ps.
