    "abstract": "We studied the ground and excited states of $^{12}$C based on variational\ncalculations after spin-parity projection in a framework of antisymmetrized\nmolecular dynamics(AMD). The calculations systematically reproduce various\nexperimental data. It was found that the sub-shell closure and SU(3)-limit\n$3\\alpha$ cluster components are contained in the ground state, while various\n$3\\alpha$ cluster structures develop in the excited states. We discussed\neffects of $\\alpha$ breaking and show the importance of coexistence of the\ncluster and shell-model-like aspects.",
