We report a resistive investigation of superconductivity in the system La2 - xSrxCuO4 - y on samples which have been analysed by thermogravimetric techniques for oxygen deficiency determination. A maximum superconductive transition temperature is observed in La2 - xSr xCuO4 - y near the tetragonal-orthorhombic phase transition, together with a resurgence of high temperature superconductivity in non-substituted La2CuO4 - y. Drastic localization effects are observed in the vicinity of x = 0.04 with no sign of superconductivity at low temperature. These observations are coherent with a simple BCS scheme with a band filling dominated by Sr-doping and localization effects dominated by an interplay between 0 vacancies and Sr-doping. This situatio...
