Abstract
The $\beta $ decay of neutron rich $^{\mathrm{76}}$Cu to levels in $^{\mathrm{76}}$Zn has been studied using 4-HPGe clover detectors at HRIBF of Oak Ridge National Lab. We have used a pure $^{\mathrm{76}}$Cu ion beam provided by the high resolution mass separator and data on $\gamma $-ray emission following $\beta $ decay including $\beta \gamma $ and $\gamma \gamma $ coincidences were obtained. Gated $\gamma \gamma $ spectra were analyzed to identify the statistically significant coincidences, and decay schemes have been developed for all daughter nuclei within the decay chain. Presented here is the case for $^{\mathrm{76}}$Cu $\beta $ decay. We have identified 58 $\gamma $ rays associated with this decay and have extended the decay scheme up to 5.6 MeV. Finally, we have compared this reconstructed decay scheme with shell-model calculations.
