Nuclear magnetic and quadrupole moments of exotic isomeric states

An overview of some recent results on nuclear moment measurements on isomer s is being given. Neutron rich isomers have been produced in a fragmentatio n reaction at GANIL. Using the spin-orientation of the fragment beam, isome ric g-factors around Ni-68 have been measured by detecting the Larmor prece ssion via the isomeric gamma -decay (TDPAD-method). Isomers in the mass A s imilar to 180 region were produced in a fusion-evaporation reaction at Louv ain-la-Neuve c. The quadrupole moment of a 5 quasi-particle isomer in the d eformed nucleus W-179 was measured using the Level Mixing Spectroscopy (LEM S) method. Both results show how details on the nuclear structure can be in vestigated via nuclear moment measurements.
