Über die Abnahme von Elektronenzentren in 60Co-γ-bestrahltem polykristallinem NaCl bei Adsorption von Gasen

  • J. R. Rabe and G. Joppien

Abstract

Ionizing radiation generates color centers in sodium chloride. On adsorption of gases on preir-radiated salt the concentration of electron centers decreases. Adsorbed azoethane partly decomposes forming nitrogen. About one to five electron centers disappear per nitrogen molecule formed depending on experimental conditions (temperature, amount of azoethane adsorbed and pretreatment of the salt). Electron centers disappear and nitrogen is formed with identical rates following first order kinetics. It is suggested that adsorbed molecules interacting with the surface cause electrons or holes to escape from their traps and eventually to recombine.
