We report the observation of superconductivity for samples with T' phase structure in the Gd2_x_J)LaxCe_vCuCK: system. The samples exhibiting superconductivity lie in a limited composition range. Among them, the sample with the composition of Gdo Laj Ceo.nCuCK, showed the maximum superconducting onset temperature of about 12 K and the maximum zero resistivity temperature of 6.5 K. The sample was of a single T' phase with the lattice parameters of g=0.3969 nm and c= 1.220 nm by X-ray diffraction analysis.
