Abstract
THE development of linear accelerators which can produce electron pulses a few µsec. long with a peak current of several hundred m.amp. and an energy of several MeV. has made possible the study of chemical reactions by techniques similar to those used in flash photolysis. A single pulse from this type of machine will deliver a dose of the order of several thousand rads to a few ml. of liquid and should in many cases produce a chemical change large enough to be easily detectable by optical absorption with a time resolution as low as 0.1 µsec. Experiments of this kind, in which the production of the benzyl radical from benzyl compounds in organic solutions was investigated, have already been described by McCarthy and MacLachlan1. I am doing some similar work on various aqueous solutions, and this communication briefly describes my apparatus and some of the preliminary results obtained with it.
