Abstract
A $\ensuremath{\beta}$-decay study of $^{77}\mathrm{Cu}$ has been performed at the ISOLDE mass separator with the aim to deduce its $\ensuremath{\beta}$-decay properties and to obtain spectroscopic information on $^{77}\mathrm{Zn}$. Neutron-rich copper isotopes were produced by means of proton- or neutron-induced fission reactions on $^{238}\mathrm{U}$. After the production, $^{77}\mathrm{Cu}$ was selectively laser ionized, mass separated, and sent to different detection systems where $\ensuremath{\beta}$-$\ensuremath{\gamma}$ and $\ensuremath{\beta}$-$n$ coincidence data were collected. We report on the deduced half-live, decay scheme, and possible spin assignment of $^{77}\mathrm{Cu}$.
