摘要：

The recent shell-model results of even-even chains of nuclei: Te-134,Te-136,Te-138, Xe-136,Xe-138,Xe-140, Ba-138,Ba-140,Ba-142, Ce-140,Ce-142,Ce-144, and Nd-142,Nd-144,Nd-146 are explored in this manuscript. The low-lying states energies, E2 and M1 transitions, are investigated using the same effective interaction based on the realistic effective field theory potential N3LO. Significant quadrupole correlations appear in the N = 86 isotonic chain, with the signature of nonaxial gamma band. This class of collectivity is interpreted within the SU(3) symmetries scheme and confirmed by constrained Hartree-Fock shell-model calculations.
