About the mechanism for paramagnetic centers formation under the radiolysis of RbNO3 and CsNO3 crystals

The accumulation of paramagnetic centers – NO2· and O·− in RbNO3 and CsNO3 crystals under γ-irradiation at 310 K and their thermal stability has been studied. The values of the initial radiation chemical yield of NO2· were calculated to be ∼2.5 × 10−2 (100 eV)−1 in both nitrates. These values for O·− are equal to 0.05 and 0.38 (100 eV)−1 for RbNO3 and CsNO3, respectively. The heating of irradiated crystals results in the decay of NO2· and O·− centers with simultaneously appearance of the ozonide ion. The mechanism for paramagnetic centers formation under γ-irradiation of RbNO3 and CsNO3 crystals has been discussed
