RIKEN Nishina Center for Accelerator-Based Science Nuclear Dynamics Research Group
Director: Tomohiro Uesaka (D.Sc.)
Research Summary

The Nuclear Dynamics Research Group pursues research activities putting primary focus on interplay of spin and isospin in exotic nuclei. Understanding nucleosyntheses in the universe, especially those in r- and rp-processes is another big goal of our laboratory. The research subjects include isospin dependences of nuclear equation of state, spin-isospin responses of exotic nuclei, new correlations at low-densities (with SAMURAI and SHARAQ spectrometers), mass measurements of short-lived nuclei (with the Rare RI Ring).
Application of the triplet-DNP technique to nuclear physics, material and life sciences is proceeding.
