Abstract

The first information on excited states in neutron-rich Zn74 populated in the β decay of Cu74 is presented. The Cu74 half-life was measured to be 1.59±0.05 s. On the basis of γ singles and coincidence measurements, a total of 19 γ rays were placed in a level scheme for Zn74 with 10 excited states up to about 3 MeV. The low-lying level structure is satisfactorily reproduced by a shell-model calculation involving active protons in orbitals between the magic numbers 28 and 50 and neutrons filling the subshell between 38 and 50.
