Abstract
The recent shell-model results of even-even chains of nuclei: , and are explored in this manuscript. The low-lying states energies, E2 and M1 transitions, are investigated using the effective interaction based on the realistic effective field theory potential N3LO. Significant quadrupole correlations appear in the isotonic chain, with the signature of nonaxial . This class of collectivity is interpreted within the SU(3) symmetries scheme and confirmed by constrained Hartree-Fock shell-model calculations.
