Abstract

Chlorite ion is selected as a solute reactive toward e(aq)-and OH. Experimentally observed G(ClO2) is reproduced by the conventional spur diffusion model in even concentrated region without considering any reactions within 10-12s. For the solutes reactive toward the quasi-free electron, an extended spur diffusion model including in sub-picosecond time range is proposed by taking account of the experimental data of picosecond pulse radiolysis, femtosecond laser photolysis and positronium formation. The formation mechanism of H2in sub-picosecond time range is proposed. The simulated results are compared with corresponding experimental data.
