Affection to nuclear structure? 　Unified effective interaction for light to heavy nuclei. 　reduction of calculation costs Previous study of the tensor force? says… In the nuclear matter, the 3E effective interaction containing the tensor force is weakened. Saturation property The tensor force might be weakened in heavy nuclei rather than in light nuclei, and inside of nuclei rather than near nuclear surface. In the perturbation theory, The incorporation of tensor force into central force is sensitive to the starting energy. ???? Tensor force might favor such a structure that the ratio of the surface is large, namely well-developed clustering structure. The effective central force changes,
