The electron spin resonance experiment has been performed in reduced ceramic samples of BaTiO_3 containing La^<3+> ions. A characteristic F-center signal was observed for the Ba/Ti ration of 1.02. This observation of F-center signal indicates strongly that some of doped La^<3+> ions substitute Ti6lt;4+> ions and act as acceptors. The effect of some monovalent and trivalent ions on the substituting sites of Gd^<3+> ions has been also investigated. It was found that for a low concentration of monovalent ions they formed "pairs" with Gd^<3+> ions at Ba^<2+> sites.
