| Outline of Final Research Achievements |
General description of shell and cluster structures is a dream of nuclear structure physics. Describing cluster states starting with shell models, including modern ab initio ones,is a big challenge of computational nuclear science. On the other hand, if we start with the cluster model, we can easily describe cluster states with much less computational efforts, but
the contribution of non-central interactions, very important in nuclear structure, vanishes if we assume simple configuration at some localized point for each alpha cluster. The real systems have both natures of shell and cluster structures and quantum mechanical mixing of these two plays a crucial role in many cases.Thus we established a unified description for the nuclear structure.Our strategy is starting with the cluster model side,contrary to standard approaches starting with the shell model side, and try to extend the model space to include shell correlations especially for the contribution of the spin-orbit interaction.
