Resolution Enhanced ESR Spectra of the Trapped Electrons in an Alkaline Ice

Abstract
The hyperfine coupling constant and the paramagnetic relaxation characteristics of e t − in the γ-irradiated NaOH ices annealed at 110°K were studied by resolution enhancement of ESR spectra. The structure of the trapping site was also studied. The resolution of enhanced spectra depends on both the annealing time and the solute concentration, but not on γ-irradiation dose. The solute concentration dependence is discussed by a simple model.
