ON THE LUMINESCENCE MINIMUM IN CERTAIN SCINTILLATOR SOLUTIONS
Journal Article
·
· Journal of Chemical Physics (U.S.)
Several scintillator solutions were examined for the luminescence minimum previously reported for the case of Co/sup 60/ gamma -irradiated cyclohexane + benzene + p-terphenyl with oxygen present. The minimum is shown to be dependent on the nature of the solvents and of the quencher. A satisfactory interpretation of the data involves the notion of energy transfer from molecules of the less-efficient ("common") solvent to the molecules of the more efficient ("better") solvent and thence to the scintillator. The latter transfer appears to involve more than one molecule of the solvent. A suggested model of the quenching process explains the existence of two classes of quenchers, one of which does not give a minimum. (auth)
