Low-velocity transient-field technique with radioactive ion beams: g factor of the first excited 2+ state in 72Zn

The 𝑔 factor of the first excited 2+ state in 72⁢Zn has been measured using the transient-field (TF) technique in combination with Coulomb excitation in inverse kinematics. This experiment presents only the third successful application of the TF method to a short-lived radioactive beam in 10 y, highlighting the intricacies of applying this technique to present and future isotope separator on-line facilities. The significance of the experimental result, 𝑔⁡(2+
1)=+0.47⁢(14), for establishing the structure of the Zn isotopes near 𝑁=40 is discussed on the basis of shell-model and beyond-mean-field calculations, the latter accounting for the triaxial degree of freedom, configuration mixing, and particle number and angular momentum projections.
