These include the 4 to 2 in Zn and the 2 to 0 and 4 to 2 in Zn. The reduced E() energies and increased E(4)/E(2) ratios at =52,54 compared to Zn attest that the magicity is confined just on the neutron number =50 only. The levels observed in Zn suggest the onset of deformation towards heavier Zn isotopes. The data were compared to state-of-the-art shell model calculations.
