Abstract

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