The growth of the V/sup 3/ band was studied in x-ray-irradiated KCl at room temperature by measuring the optical absorption as a function of x-ray dose. In the region in which the F band grows linearly with time (after the initial fast coloration''), the V/sub 3/ band height increases approximate1y as the square root of the time. The V/sub 3/ band growth rate varies with x-ray intensity and depth in the crystal in the same way as that of the F band, however. Although the F band can be optically bleached without affecting the V/sub 3/ band, if the F band is optically bleached during the x-ray irradiation, the V/sub 3/ band likewise fails to grow. These facts are likely to be consistent with a model of the V/sub 3/ center in which a Cl/sup -/sub 3/ molecular ion is located at a cation vacancy. The center could be formed by the x-ray production of an anion vacancy-interstitial pair and the diffusion of a cation vacancy to the interstitial. (auth)
