In-gas-cell laser spectroscopy of the isotopes 57,58,59,63,65Cu has been performed at the LISOL facility using the 244.164-nm optical transition from the atomic ground state of copper. A detailed discussion on the hyperfine structure of 63Cu is presented. The magnetic dipole moments of the isotopes 57,58,59,65Cu are extracted based on that of 63Cu. The new value μ = +0.479(13)μN is proposed for 58Cu, consistent with that of a πp3/2 x νp3/2 ground-state configuration. Spin assignments for the radioactive isotopes 57,58,59Cu are confirmed. The isotope shifts between the different isotopes are also given and discussed.
