Abstract

A β-decay study of the even mass ${}^{74, 76, 78}{Cu}$ isotopes toward levels in ${}^{74, 76, 78}{Zn}$ was performed at the ISOLDE mass separator. The copper isotopes were produced in proton- or neutron-induced fission reactions on ${}^{238}U$ , laser ionized, mass separated, and sent to a $β - γ$ detection system. Half-lives, decay schemes, and possible spin configurations were obtained for the copper isotopes. The results are compared with calculations using schematic forces as well as large-scale shell-model calculations with realistic forces.
