Objective is the study of protonic conduction in perovskite oxides, such as KTaO/sub 3/. Doped crystals of this material readily incorporates interstitial H/sup +/. The D/sup +/-H/sup +/ isotope effect was measured in Ni/sup 3 +/ and Co/sup 3 +/-doped KTaO/sub 3/. The defect structure of pure and doped KTaO/sub 3/ was studied using EPR, dielectric relaxation, and nonstoichiometry. Other studies underway include Sc/sub 2/O/sub 3/-doped ceria, dielectric relaxation in borate glasses, and preexponentials of conductivity in fast-ion conductors. (DLC)
