Online measurements of the magnetic dipole moments and isotope shifts of 58Cu and 59Cu by the in-source laser spectroscopy method are reported. The results for the magnetic moments are μ (58Cu) =+0.52(8) μN,μ(59Cu) =+1.84(3) μN and for the isotope shifts δν59,65=1.72(22) GHz and δν58,65=1.99(30) GHz in the transition from the 3d104s 2S1/2 ground state to the 3d104p 2P1/2 state in Cu I. The magnetic moment of 58Cu is discussed in the context of the strength of the subshell closure at 56Ni, additivity rules and large-scale shell model calculations.
