Abstract

Within the shell-model framework, we have derived a new effective interaction from the realistic N3LO interaction to provide an accurate description of the nuclear structure properties of even-even nuclei with $50 \leq Z, N \leq 82$ , in the ${}^{132}{Sn}$ mass region. We validate our theoretical framework and the reliability of the new effective interaction by comparing the calculated energy levels, $E 2$ transition rates, and magnetic dipole moments with experimental data. Special attention is devoted to the evolution of collectivity; an in-depth study of the quadrupole properties of different nuclei in this region reveals the presence of triaxial $γ$ bands.
