• Optical absorption and emission of the F_B centers were investigated for KCl, KBr and RbCl crystals heavily doped with sodium. A new emission band was discovered at 0.49 eV and 0.42 eV with narrow band-width in KCl and RbCl, respectively. By comparing the optical abosorption energies as inferred from the excitation spectra with those predicted by Wong and Wang, the center responsible for the emission is considered to be a new type of the F_B center consisting of a triangular configuration of an F center and two Na^+ ions. The emission behavior suggests that the emission may occur from the saddle configuration as has as been proposed for the type I-F_A center by Luty. The properties of F_C centers are also given briefly.
