Abstract
The β decay of neutron-rich Cu74 has been studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. By using a high-resolution mass separator a purified Cu74 beam was obtained, thus allowing decay through its isobar chain to stable Ge74 without any decay chain member dominating. A total of 170γ rays were associated with Cu74β decay with 111 placed in the Zn74 level scheme. Updated β feeding intensities and estimated log(ft) values are presented, and new Jπ assignments are proposed using shell model calculations. The progression of simulated total absorption γ-ray spectroscopy (TAGS) based on proposed levels and β-feeding values from previous measurements to this evaluation are presented and demonstrate the need for a TAGS measurements for this and similar decays.
