Apparstus is described for fast electron-beam excitation of organic scintillstors. A special cathode-ray tube is used to provide a beam currert of 1 ma st up to 55 kv. The electron-beam apparatus is used to study the nise time of the scintillation pulse in scintillator solutions of anthracene in benzene and p- terphenyl in toluene. The theory of energy transfer in liquid solutions of Kallmann and Furst predicts a dependency of rise time on concentration. The rise time is a measure of the rate of filling of excited levels in the scintillator solute by energy transfer from the initially excited solveat. Observed rise-time variations agree with the theory of Kallmaru and Furst. (auth)
