RESEARCH ON RADIATION-INDUCED FREE RADICALS OF SHORT LIFETIME
Abstract
The detection and study of short-lived free radical intermediates produced by beams of highenergy electrons are described. The Stanford Mk IV electron linear accelerator was the source of high energy electrons and the detection method employed the techniques of electron paramagnetic resonance (epr) spectrometry. Technical problems associated with the study of the kinetics of free radical intermediates when these are produced by beams of high energy electrons are examined. These problems arise from the fact that one wishes to irradiate a given sample, but inevitably must irradiate other components of the system such as the cavity and sample holder (if there is one); the result is interference with the detection apparatus. Another problem arises from lack of sufficient radiation dose in the sample during a pulse. The indications were that in sufficient concentrations, shorter lived events, to approximately 0.2 sec would be detectable by the same apparatus. (Author)
