The experiment was ran at REX-ISOLDE, CERN, and the -ray perturbed angular correlations were measured using 4 triple Germanium clusters of the Miniball array. The experimental result (2) = +0.47(14) is significant to establish the structure of the Zn isotopes near N=40. Comparison with shell-model calculations reveal that to reproduce the measured energies and B(E2) of the Zn isotopes around N=40, both the proton excitations from the orbit and neutron excitations into the and orbits are essential. Furthermore, beyond-mean-field calculations reveal the need to include the triaxial degree of freedom.
