Study of α/β ratios of organic scintillation solutions

The ratio of alpha -stimulated to BETA -stimulated luminescence, the alpha / BETA ratio, was studied in binary and ternary organic scintillation solutions. The ratio was found to vary with the decay time of the solvent and/or the solute. To explain the low fluorescence yield under alpha -particle excitation, transient free radicals produced along the alpha track are assumed to contribute to the dynamic quenching parameter. (auth)
