    Abstract

    This paper reports on the ground state nuclear moments measured in 58-62Cu using collinear laser spectroscopy at the ISOLDE facility. The quadrupole moments for 58-60Cu have been measured for the first time as Q(Cu58)=-15(3) efm2, Q(Cu59)=-19.3(19) efm2, Q(Cu60)=+11.6(12) efm2 and with higher precision for 61,62Cu as Q(Cu61)=-21.1(10) efm2, Q(Cu62)=-2.2(4) efm2. The magnetic moments of 58,59Cu are measured with a higher precision as μ(Cu58)=+0.570(2)μN and μ(Cu59)=+1.8910(9)μN. The experimental nuclear moments are compared to large-scale shell-model calculations with the GXPF1 and GXPF1A effective interactions, allowing the softness of the 56Ni core to be studied.
