EFFECTS OF OH^- IONS ON THE FORMATION AND THERMAL DECAY PROPERTIES OF F-AGGREGATE CENTERS IN LIGHTLY DOPED LiF: OH^-

Under identical irradiation conditios, higher concentrations of F⁺₂, F^-₂, and F₂ centers in lightly doped LiF: OH^- than in pure LiF are found, but thermal stability of F⁺₂ center in these two samples is almost the same. Products of OH^- decomposition play an important roles in the formation and thermal decay processes of these F-aggregate centers.
