简介: Pion exchange interaction that is the most important interaction for binding nuclei has the tensor forces with the same amplitude as
the central forces. However, except for very light nuclei such as deuteron and 4He, the tensor forces have not been included explicitly for
making models of nuclei. The most successful models of nuclei such as shell model or mean field model uses only central forces in the basic
interaction and tensor forces are treated as perturbation.
Recent studies of nuclei in wide range of A/Z present a behavior that can be explained only by the inclusion of tensor forces.
In this talk importance of tensor forces in nuclei are first reviewed and then the recent studies to observe direct evidences of tensor
forces will be presented.
