Atomic Nuclei in 2002: Surprises, discoveries and evolutions

UNIVERSITE DE GENEVE Stückelberg Auditorium

In this talk we will show how the study of nuclei under extreme conditions have changed our understanding of atomic nuclei. Indeed in the past 10 years unexpected results and important discoveries have shown how far nuclear models are from a realistic picture. Hot nuclei have renewed our understanding of phase transitions infinite systems in particular with the observation of negative heat capacities. This anomalous behaviour has now been observed in other mesoscopic systems such as metallic cluster. Exotic nuclei have contradicted the paradigm of the nucleus as a homogeneous quantum drop of nucleons. The discovery of halo and molecular nuclei as well as the observation of the disappearance of magic number in neutron rich regions of the nuclear chart are some example of the actual 'nuclear structure crisis.
