Abstract
The g values for the primary species formed in the γ-radiolysis of light and heavy water have been measured as a function of temperature up to 300 °C. With the exception of g(H2) and g(D2), all the g values are consistent with the generally accepted diffusion-kinetic model of spurs, i.e. with an increase in temperature, the g values of the free radicals increased while those of peroxide decreased. The g values for H2 and D2 increased with temperature which suggests that they are formed by other mechanisms in addition to radical–radical reactions in the spur.Keywords
