Abstract
IN a recent paper1 we showed how paramagnetic relaxation experiments can give new insights into the nature of the trapping sites of trapped radicals and ions. Trapped electrons in irradiated alkaline ices show no change in their relaxation time over a range of radiation dose from 0.2 to 3 Mrads; this implies that the electrons are trapped in spurs1. This communication reports relaxation time measurements on trapped hydrogen atoms which show just the opposite effect; the relaxation time decreases with dose in the range O.5–5 Mrads.
