Show affiliationsThe stability of rotating nuclei against fission through creviced shapes is investigated within the generalized liquid-drop model including the nuclear proximity energy. The potential barrier corresponds to large deformations hindering the fission process even at very high spins. At intermediate angular momenta, the deformation energy is relatively constant up to beta approximately 0.7 and shell effects can generate secondary minima where superdeformed states may survive. With increasing spins, the potential pocket moves towards the barrier foot leading to hyperdeformed equilibrium shapes. The characteristics of these quasi-molecular nuclear systems are given in the whole mass range. For an intermediate nuclear mass, asymmetric fusion allows the potential surface to be penetrated more deeply and higher spins to be reached.
