在反对称化分子动力学(AMD)的框架下，用变分计算研究了12C自旋宇称投影后的基态和激发态。这些计算系统地再现了各种实验数据。我们发现基态中含有亚壳层封闭和SU(3)限制的3α团簇成分，而在激发态中形成了各种3α团簇结构。我们展示了α团簇破缺在α团簇的3个态和基态中的重要性。
We study the ground and excited states of12C employing variational calculations after spin-parity projection in the framework of antisymmetrized molecular dynamics (AMD). The calculations systematically reproduce various experimental data. We find that the sub-shell closure andSU(3)-limit 3αcluster components are contained in the ground state, while various 3αcluster structures develop in the excited states. We show the importance ofα-cluster breaking in the 3αcluster states as well as the ground state.
