title = "Temperature reversible Self-Trapped Holes in fictive temperature-treated silica",
abstract = "Post-mortem EPR spectroscopy has been carried out to examine the radiation-induced Self-Trapped Hole (STH) in fictive temperature (T<inf>f</inf>) treated Heraeus F300 silica. By repeating isochronal annealing cycles between 77 and 300 K, we observed that STH decreases with T but in a reversible manner. We evidenced a deviation from the Curie law for T > 70 K and suggest an interpretation based on the decrease of a “strain-assisted Trapped Holes“ population by a reversible excitation of the trapped hole to a delocalized state with activation energy of 7.8 meV.",
