The long-standing discrepancy between the kinetics of the hydrated electron measured in pulse radiolysis experiments and the time dependent decay inferred from the inverse Laplace transform of scavenger data is resolved by the incorporation of an improved measurement of the rate coefficient for the CH{sub 3}Cl + e{sub aq}{sup -} reaction used in the inverse Laplace transform treatment. The revised analysis of both data types leads to the conclusion that the spatial distribution of secondary electrons produced in the energetic electron radiolysis of water is nearly twice as wide as suggested by previous studies. 38 refs., 2 figs.
