Abstract
Crystal structure, oxygen stoichiometries and superconducting properti es of RT chemically oxidized La2-xSrxCuO4+y (0 < x < 0.15) have been s tudied by means of powder neutron diffraction, thermogravimetric analy sis and magnetic susceptibility measurements. The presence of intersti tial oxygen located at (1/4,1/4,approximate to 1/4), as in La2CuO4+y, is confirmed; however, phase separation at low temperature is not obse rved.
