Abstract:

In the framework of the semi-empirical quark model of nuclear structure, SCQM-FCC, that is based on the quark model of the nucleon, the Strongly Correlated Quark Model (SCQM) we construct nuclei from light to heavy ones, including halo nuclei. Nucleons inside nuclei are bound due to junctions of SU(3) color fields of quarks. According to SCQM, arrangement of nucleons within nuclei reveals the emergence of the face-centered cubic (FCC) symmetry. The model of nuclear structure becomes isomorphic to the shell model and, moreover, composes the features of cluster models. Binding of nucleons in stable nuclei are provided by quark loops which form three and four nucleon correlations. Quark loops leading to four-nucleon correlations are responsible for the binding energy enhancement in even-even nuclei which are composed by virtual alpha-clusters. The model describes the “magic” numbers without spin-orbital coupling of the shell model. The model allows to describe nuclear deformation that is in a good agreement with experimental values of electric quadrupole moments.
