Abstract : Studies in the following areas are summarized: light absorption in the presence of excited states (strongly populated using a Q-switched laser) in KI, CsI, and RbBr; lifetimes of the relaxed excited state of F-centers in KI, CsI, RbBr, and CsF; absorption edge of I(-) in KBr single crystals; process of F-center formation with ultraviolet light of mixed and pure alkali halides.
