The deformation-dependence of clusterization in atomic nuclei is investigated. In particular, allowed and forbidden cluster-configurations are determined for the ground, superdeformed, and hyperdeformed states of some light and heavy nuclei, based on a microscopic (real and effective SU (3)) selection rule. For light nuclei the real U (3) symmetry is used to characterize the parent and cluster nuclei. In the case of heavy nuclei our study is based on the application of the effective U (3) symmetry, which was first introduced for nuclei with large prolate deformation [1]. The stability of the different cluster configurations from the viewpoint of the binding energy [2] is also investigated for comparison.
