摘要

By heating LiCsSO4 crystals which have been doped with ammonium chromate and γ-irradiated, Cr3+ species with large zero-field splittings were detected by electron spin resonance (ESR). The Cr3+ species result from an ammonium-hydrogen-assisted dissociation of the CrO43- and CrO3- species produced by irradiation. The same oxygen-stripping effect was observed by ESR in γ-irradiated LiNH4SO4 and (NH4)2SO4 crystals doped with CrO42-. Dissociation of CrO42- itself into Cr3- was observed by ESR in CrO42--doped ammonium sulfate crystals heated at temperatures well below the dissociation temperature of this compound.
