Moments of Exotic Nuclei — •Gerda Neyens — K.U. Leuven, Instituut voor Kern- en Stralingsfysica, Leuven, Belgium

Magnetic dipole moments and electric quadrupole moments are fundamental properties of nuclei. They reveal information about the nuclear structure and about the interaction that holds the nucleons together in the atomic nucleus. As the electrons in atoms, the nucleons (protons and neutrons) in the atomic nucleus can be described as moving in a mean field induced by the other nucleons. However, while the atomic electrons are interacting through the well-known electromagnetic interaction, the description of the nuclear forces is less understood and *effective* interactions are being used to model the nuclear properties. Not only do nuclear moments allow to test the validity of nuclear model predictions, these parameters can also serve as an input to improve on the parametrisation of the models.

In this talk, I will present recent experimental developments and results from moments measurements on exotic isotopes produced by projectile fragmentation and by the ISOL method.
