Magnetic dipole moments of ^{57,58,59}Cu

In-gas-cell laser spectroscopy of the isotopes Cu-57,Cu-58,Cu-59,Cu-63,Cu-65 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 Cu-63 is presented. The magnetic dipole moments of the isotopes 57,58,59,65Cu are extracted based on that of 63Cu. The new value mu = +0.479(13) mu(N) is proposed for Cu-58, consistent with that of a pi p(3/2) circle times nu p(3/2) ground-state configuration. Spin assignments for the radioactive isotopes Cu-57,Cu-58,Cu-59 are confirmed. The isotope shifts between the different isotopes are also given and discussed.
