Relative rates of reaction of electrons produced in gamma-irradiated zeolite (Molecular Sieve 13X) with several electron scavengers were determined by competition kinetics using dinitrogen monoxide as a reference compound. A part of the electrons produced in irradiated zeolite have been disclosed to be quasi-free from the feature of their reactivity toward electron scavengers that the reactivity is similar to that of quasi-free electrons found in irradiated liquid 2,2-dimethylpropane. An analysis based on competition kinetics has provided a value 9.8×10<SUP>12</SUP> dm<SUP>3</SUP> mol<SUP>−1</SUP> s<SUP>−1</SUP> as the lower limit on the rate constant for the reaction of quasi-free electrons with positive holes produced in irradiated zeolite.
