Abstract:

This is a final report of research designed to extend the knowledge of production, storage and utilization of highly energetic chemical species. The research concentrated on the physical and chemical properties of radiation-produced ions trapped in solid matrices. The first definitive and comprehensive picture of trapped electron energy levels in glassy matrices extending over a broad range of polarity has been obtained from both experimental and theoretical studies. Mobility measurements of electrons in conduction states of glassy matrices have allowed the identification of the dominant electron scattering mechanisms. New methods involving electron-electron double resonance have been developed to study magnetic energy transfer between ions and radicals in disordered solids. The spatial correlation between cations and electrons produced by photoionization has been demonstrated to depend upon the photoionization energy. These studies lay the groundwork for characterizing the stability of ion trapping in disordered solids. Included are abstracts of 34 papers completed on this project. Modified author abstract
