| Research Abstract |
The nucleus is formed by the one-pion exchange potential(OPEP) between protons and neutrons. In this study, we investigate the role of the OPEP, which contains the non-central component. We first develop the theoretical method to treat the OPEP in nuclei and next apply this method to analyze the structures of light nuclei. From the results, it is found that the OPEP plays a decisive role to explain the excitation energy spectra. In addition, we also predict the many-body resonances observed in neutron-rich unstable nuclei and investigate the structures of those resonances.
