Abstract

Online measurements of the magnetic dipole moments and isotope shifts of ${}^{58}{Cu}$ and ${}^{59}{Cu}$ by the in-source laser spectroscopy method are reported. The results for the magnetic moments are $μ$ ( ${}^{58}{Cu}$ ) $= + 0.52 (8) μ_{N}, μ$ ( ${}^{59}{Cu}$ ) $= + 1.84 (3) μ_{N}$ and for the isotope shifts $δ ν^{59, 65} = 1.72 (22)$ GHz and $δ ν^{58, 65} = 1.99 (30)$ GHz in the transition from the $3 d^{10} 4 s$ ${}^{2}S$ $_{1 / 2}$ ground state to the $3 d^{10} 4 p$ ${}^{2}P$ $_{1 / 2}$ state in Cu I. The magnetic moment of ${}^{58}{Cu}$ is discussed in the context of the strength of the subshell closure at ${}^{56}{Ni}$ , additivity rules and large-scale shell model calculations.
