【 摘 要 】

I discuss an algebraic treatment of alpha-cluster nuclei in the framework of the Algebraic Cluster Model. It is suggested to treat12C as an oblate top with symmetry (equilateral triangle) and16O as a spherical top with tetrahedral symmetry (regular tetrahedron). The structure of the rotational bands is a consequence of the underlying symmetry, and can be used to help determine the geometrical configuration of the α-particles.
