The crystal structure, superconducting properties and oxygen stoichiometry of room temperature chemically oxidized La2\_~grxCuO4+y (x= 0.05, 0.09) have been studied by means of powder neutron diffraction, magnetic susceptibility and thermogravimetric analysis. The presence in these materials of inte
