Description of Deformed Nuclei in a Quark-Meson Coupling Model with Tensor Coupling
Abstract
We extend the quark-meson coupling model to study the ground-state properties of axially deformed even-even nuclei. For this purpose, we introduce ω-N tensor coupling to the model Lagrangian and obtain the parameters from fits to the experimental data for finite nuclei. The present work is mainly focused on the nuclei in the rare-earth region. The ground-state binding energies, quadrupole deformations, shape coexistence, two-neutron separation energies and the root-mean-square charge radii are calculated and compared with the experimental data. It is shown that this extended quark-meson coupling model can give a reasonable description of the axially deformed nuclei.
