Evolution of the nuclear structure approaching $^{78}$Ni: $\beta$ decay of $^{74-78}$Cu

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

Descripción
Sumario:A beta -decay study of the even mass /sup 74,76,78/Cu isotopes toward levels in /sup 74,76,78/Zn was performed at the ISOLDE mass separator. The copper isotopes were produced in proton- or neutron- induced fission reactions on /sup 238/U, 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.
