The influence of track structure on chemical yields was studied for high LET radiation in nonpolar materials. The time-resolved fluorescence of benzene in cyclohexane irradiated by pulsed proton beams (0.85 to 13 MeV) show that the fluorescence decay becomes more nearly exponential with proton energy. Benzene fluorescence excited by pulsed alpha particles is quenched significantly less than that excited by pulsed protons; the difference in the radial distribution of absorbed energy is one possible explanation. The stochastic model of track structure can be used to explain the difference in the yield of hydrated electrons produced in aqueous solutions by pulsed alpha particles and deuterons of the same stopping power. 3 figures.
