Abstract: The impact of the tensor force on the properties of finite nuclei is discussed by analyzing the spinorbit splittings and the multipole giant resonances in nuclei. It is found that the tensor force do plays an important role in nuclear structure. The experimental isospin dependence of the spinorbit splitting is very well depicted when the tensor force is included. The tensor force has a larger
effect on the spin flip magnetic dipole states than on the natural parity isoscalar quadrupole(2+) states. By analyzing the modifications to the HartreeFock mean field induced by the tensor terms，and the specific features of the residual particlehole tensor interaction，we find that the tensor force gives an
attractive contribution to the particlehole matrix elements.
