| Outline of Final Research Achievements |
An importance of tensor forces in the structures of ground states of nuclei has been studied. Effects of tensor forces were observed in many features of structures such as magnetic moment, level mixing, high-momentum nucleons and pn correlations.
Important findings of present studies were: (a) the observation of a high-momentum component of neutrons in the ground state of 16O nucleus as expected by the tensor force , (b) it was found that such a high-momentum neutron is correlated with a proton in a nuclei with S=1, T=0 channel that is consistent with the tensor forces, (c) mixing of single orbitals in extremely neutron rich nuclei were observed and understood as the effect due to 2p2h mixed configurations by tensor forces, (d) The TOSM model, that include the effects of tensor forces explicitly, was developed and applied to light nuclei, (e) TOAMD model, that not only includes the tensor forces explicitly but also include cluster structure naturally, has been developed.
