Spins and electromagnetic moments of 101-109Cd

The neutron-deficient cadmium isotopes have been measured by high-resolution laser spectroscopy at CERN-ISOLDE. The electromagnetic moments of Cd-101 have been determined for the first time and the quadrupole-moment precision of Cd-103 has been vastly improved. The results on the sequence of 5/2(+) ground states in Cd101-109 are tentatively discussed in the context of simple structure in complex nuclei as similarities are found with the 11/2(-) states in the neutron-rich cases. Comparison with shell-model calculations reveals a prominent role of the two holes in the Z = 50 core.
