Title: Updated β -decay measurement of neutron-rich Cu 74

Abstract

Here, the β decay of neutron-rich 74Cu has been studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. By using a high-resolution mass separator a purified 74Cu beam was obtained, thus allowing decay through its isobar chain to stable 74Ge without any decay chain member dominating. A total of 170γ rays were associated with 74Cuβ decay with 111 placed in the 74Zn level scheme. Updated β feeding intensities and estimated log(ft) values are presented, and new J π 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.
