Shape isomers of α-like nuclei in terms of the multiconfigurational dynamical symmetry

NUCLEAR STRUCTURE ¹²C, ¹⁶O, ²⁰Ne, ²⁴Mg, ²⁸Si, ³²S, ³⁶Ar, ⁴⁰Ca, ⁴⁴Ti; calculated energy spectra, shape isomers in the α-like nuclei, selection rules to determine possible binary clusterizations for different states of 4N-nuclei, reciprocal forbiddenness as a function of the mass number of the lighter cluster for the shape isomers. Shape isomers obtained from the stability and self-consistency of the quasidynamical SU(3) symmetry (or quadrupole deformation). Comparison to the predictions from the energy surface method (BB and Nilsson models).
