Light emission from water irradiated with high energy electrons Shaede, Eric Albert


Luminescence has been observed from water Irradiated with an intense pulse of high energy electrons. The angular dependence, electron energy dependence, visible spectrum, lifetime and yield of the light emission have been determined. In addition, the effect of additives on the emission was studied. The emission spectrum of water was found to be identical to that of methanol, oyclohexane and benzene. All of these results lead to the conclusion that no light emission other than Cerenkov radiation was present in the visible region of the spectrum. The yield of Cerenkov radiation was found to be GhV(4-5000Å)~6x10-4.
