Abstract :
A study of the time dependence of the radiolytic yields of the hydrated electron (eaq−) produced with nanosecond pulses of high linear energy transfer (LET) particles is presented. Pulses of 95 MeV/amu 16O8+ and 36Ar18+ are used. Their respective LET values are 50 ± 1 and 271 ± 5 eV/nm. The g-values of eaq− at 10 ns and even 1 ns, 5.9 × 10−9 mol J−1 with Ar18+, are compared to those obtained with C6+. Because of the same velocity of these ions (β=0.4), the g-values are interpreted in terms of picosecond–time scale reactions of high concentrations of radicals (0.16 M) in the track cores.
