Title:     New Aspects of the Structure of Exotic Nuclei

Abstract: The structure of nuclei far from the stability line is a central theme of research in nuclear physics. Key to the success of this program has been the worldwide development of radioactive beam facilities and novel detector systems, which provide the tools needed to produce and study these nuclei.

Some of the interesting questions we are trying to answer are related to:
- The evolution of shell structure with isospin,
- The characterization of the elementary modes of excitation in neutron rich nuclei,
- The role of isoscalar neutron-proton pairing along the N=Z line, and
- The structure of the very heavy elements.

In this talk I will present recent results from our group that shed light on these new aspects of nuclear structure. They include: i) Experiments carried out at NSCL/MSU to measure the quadrupole collectivity in neutron rich carbon isotopes and in the region around 64Cr, and ii) A study of the 44Ti(3He,p) at the ATLAS facility at ANL to address the question of np pairing. I will end the presentation with a short review of the gamma-ray tracking technique. LBNL has been leading the US effort in the development of GRETINA, a spectrometer based on this technique. The status of the project and the exciting physics opportunities that are possible with this instrument will be discussed.

The NRC-IFCI is located at 4250 Wesbrook Mall near the intersection with Southwest Marine Drive. Stimulants available 15 minutes before the talk.
