Magnetic and quadrupole moments of neutron deficient $^{58-62}$Cu isotopes

This paper reports on the ground state nuclear moments measured in (58-62)Cu using collinear laser spectroscopy at the ISOLDE facility. The quadrupole moments for (58-60)Cu have been measured for the first time as Q ((58)Cu) = 15(3) efm(2), Q ((59)Cu) = -19.3(19) efm(2), Q((60)Cu) = +11.6(12) efm(2)...

Sumario:This paper reports on the ground state nuclear moments measured in (58-62)Cu using collinear laser spectroscopy at the ISOLDE facility. The quadrupole moments for (58-60)Cu have been measured for the first time as Q ((58)Cu) = 15(3) efm(2), Q ((59)Cu) = -19.3(19) efm(2), Q((60)Cu) = +11.6(12) efm(2) and with higher precision for (61.62)Cu as Q ((61)Cu) = -21.1(10) efm(2), Q((62)Cu) = -2.2(4) efm(2). The magnetic moments of (58.59)Cu are measured with a higher precision as(IL)((58)Cu) = +0.570(2)(ILN) and (IL)((59)Cu) = +1.8910(9)(ILN). The experimental nuclear moments are compared to large-scale shell-model calculations with the GXPF1 and GXPF1A effective interactions, allowing the softness of the (56)Ni core to be studied.
