Symplectic symmetry and clustering in atomic nuclei

A new symplectic-based shell-model approach to clustering in atomic nuclei is proposed by considering the simple system ${}^{20}$Ne. Its relation to the collective excitations of this system is mentioned as well. The construction of the Pauli allowed Hilbert space of the cluster states with maximal permutational symmetry is given for the ${}^{16}$O+${}^4$He $\to$ ${}^{20}$Ne channel in the case of one-component many-particle nuclear system. The equivalence of the obtained cluster model space to that of the semi-microscopic algebraic cluster model is demonstrated.
