THE ANALYSIS OF CHLORINE SIGNAL DECAY IN ELECTRON-IRRADIATED SODIUM-CHLORIDE

We present measurements of the chemical decomposition rate of electron irradiated NaCl as a function of incident electron energy. It is show n that although the chlorine signal decay varies with electron energy as expected from Bethe stopping, the absolute decay rate is an order o f magnitude slower than anticipated from the measured G values. A simp le model is presented which allows an estimate to be made of the jump distance associated with the formation and recombination of F-H center pairs, The experimental measurements suggest that in NaCl this distan ce is 15 nm.
