Abstract

Nuclear Physics aims at understanding the fundamental properties of the constituents of matter. These are essential to our understanding of the origin and evolution of elements in the universe. Most of the stable nuclei found on earth are created from the decay of unstable nuclei in the stars. The availability of short-lived nuclei produced at the radioactive-isotope beam (RIB) facilities worldwide in recent years have advanced our knowledge on the limits of nuclear stabilities and the properties of rare nuclei with very unusual proton-to-neutron compositions. New phenomena, such as emergence of new magic numbers, neutron halos and skin, have been discovered in nuclei far from stability, and more discoveries are expected with the new generation of RIB accelerators including RIKEN Nishina Center (Japan) and other facilities under construction in US, France and Germany.

To understand the new properties of these unstable isotopes, it is essential to obtain a detailed knowledge of correlations between nucleons and the transitions in correlation mechanisms from the stability to instability. In this talk, I will present experimental methods and frameworks established by our group to probe nucleon correlations at the world’s leading facilities, especially at RIKEN. I will also show our recent experimental results and future plans.

Coffee and tea will be served 20 minutes prior to the seminar.
