Radiation-induced radical ions in calcium sulfite
We have used EPR to study the effect of γ radiation on calcium sulfite. We have observed and identified the radiation-induced radical ions SO2−(iso) with g = 2.0055 and SO2−(orth-1) with g1 = 2.0093, g2 = 2.0051, g3 = 2.0020, identical to the initial and thermally induced SO2− respectively, SO3− (is...

Zusammenfassung: | We have used EPR to study the effect of γ radiation on calcium sulfite. We have observed and identified the radiation-induced radical ions SO2−(iso) with g = 2.0055 and SO2−(orth-1) with g1 = 2.0093, g2 = 2.0051, g3 = 2.0020, identical to the initial and thermally induced SO2− respectively, SO3− (iso) with g = 2.0031 and SO3−(axial) with g⊥ = 2.0040, g∥ = 2.0023, identical to mechanically induced SO3−. We have established the participation of radiation-induced radical ions SO3− in formation of post-radiation SO2−. |
