Abstract:

A beta-decay study of the even mass Cu-74,Cu-76,Cu-78 isotopes toward levels in Zn-74,Zn-76,Zn-78 was performed at the ISOLDE mass separator. The copper isotopes were produced in proton- or neutron-induced fission reactions on U-238, laser ionized, mass separated, and sent to a beta-gamma 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.
