Abstract: Recently reported nuclear spins and moments of neutron-rich Zn isotopes measured at ISOLDE-CERN [C. Wraith et al., Phys. Lett. B 771, 385 (2017)] show an uncommon behavior of the isomeric state in 73Zn. Additional details relating to the measurement and analysis of the 73mZn hyperfine structure are addressed here to further support its spin-parity assignment 5/2+ and to estimate its half-life. A systematic investigation of this 5/2+ isomer indicates that significant collectivity appears due to proton/neutron E2 excitations across the proton Z = 28 and neutron N = 50 shell gaps. This is confirmed by the good agreement of the observed quadrupole moments with large scale Monte Carlo shell model calculations. In addition, potential energy surface calculations in combination with T plots reveal a triaxial shape for this isomeric state.
