Optical-absorption measurements show that substitutional H^- ions (that is, protons on anion sites each with two electrons) are thermally more stable than anion vacancies when thermochemically reduced CaO samples are annealed in a reducing atmosphere. Electron irradiation decreases the concentration of H^- ions and increases the concentration of oxygen vacancies with a cross section much larger than for elastic collision damage. The room-temperature lifetime of the 2.1-eV F-center luminescence decreases as the concentration ratio of F centers to H^- ions increases.
