The positron lifetime spectra in 0.25 at.% La-doped BaTiO, with different Ba/Ti ratios have been measured at room temperature. It was found from the experiments that with deviating from exact stoichiometry the positron lifetime z2 decreases and the intensity I , increases for Ba/Ti ratio smaller tha
