Abstract

1. The radical products in irradiated frozen solutions of KOH in H2O and D2O were investigated by the electron paramagnetic resonance method at various concentrations and in the temperature range from −196 to −100°. 2. Stabilization of the hydrated electron and conversion of the OH radical to the ion radical O− · nH2O occur in alkaline medium. 3. H and D atoms were detected in irradiated concentrated frozen solutions of KOH in H2O and D2O at −196° 4. The thermal stability of the radical products in neutral water and in solutions of alkali of various concentrations was investigated. 5. The yields of radical products in alkaline medium were determined at temperatures of −196 and −150° as a function of the KOH concentration, and they were found to be increased in comparison with neutral frozen water.
