【 摘 要 】

Important roles of the NN interaction in the shell evolution, which have been pointed out by Otsuka and his collaborators, can be investigated by the self-consistent mean-field approaches with the semi-realistic interactions. We show that the shell evolution in the Z = 50 and Z = 20 nuclei is appropriately described by the semi-realistic interactions that include the realistic tensor force. The M1 strengths in208Pb are also reproduced by the semi-realistic interactions in the HF+RPA, which are another manifestation of the tensor force in nuclear structure.
