• A study was made on absorption and emission spectra of Ag^- centers in KCl crystals. By inspecting the excitation spectra for emission, two new bands were found at 3.11 and 3.27 eV in addition to the previously known 4.36 eV absorption band. These three bands, named A, B, and C, are ascribed to transitions ^1S_0&roar;^3P_1, ^3P_2 and ^1P_1 respectively. Besides the 2.93 eV emission, another emission band was discovered at 4.08 eV. They are attributed to transitions ^3P_1 and ^1P_1&roar;^1S_0. Energy parameters and electron-lattice coupling constants specifying the configuration-coordinate surfaces were determined from the peak energies, second moments, and Stokes shifts of the observed spectra. Data on the degree of polarization suggest that a trigonal lattice deformation is dominantly realized in each of the relaxed ^1P_1 and ^3P_1 states. The shape of the C band and the ratio of life times for the ^1P_1 and ^3P_1 states are in reasonable agreement with theory.
