| Research Abstract |
In nuclear systems, it has been known that two non-central interaction, namely spin-orbit and tensor interactions, strongly act. The competition between their contributions plays an essential role in the structure change of nuclei as functions of excitation energy and proton/neutron numbers. In the present study, we proposed new models to discuss it and also combined conventional nuclear structure/reaction models and shown that, in the excited states of neutron-rich nuclei, a new structure, geometric configurations of clusters stabilized by neutrons, appears.
