In this work; effects of tensor force on the evaluation of shell structure of Z = 28 and Z = 82 isotopes are investigated in the framework of Hartree-rock+BCS approach. Skyrrne type SLy5 and SIII interactions are used with and without tensor interaction. The effect of tensor force on the gap evaluation, single particle energies and spin-orbit splittings of the selected isotopic chain are presented. Pairing energy results are also discussed. It is shown that tensor force plays a crucial role in the evaluation of the single particle states and changing spin-orbit splittings of Nickel and Is ad isotopic chain.
