Light nuclei show evidence for a U(3) symmetry. This symmetry appears in all of the basic models of these nuclei, such as the shell, collective and cluster model. It has a microscopic origin which is related to the shell structure and to the nature of the effective two-nucleon forces, but it determines macroscopic characteristics as well, such as the amount of quadrupole deformation, moment of inertia, etc. We show that this symmetry also serves as a basis for interrelating various cluster configurations of the same (compound) nucleus, offering a natural link between seemingly unrelated phenomena, like nuclear molecular resonances and excitations in the low-lying nuclear spectra.
