Radioactive Ion Beam Physics Group

Brief Introduction

The Radioactive Ion Beam Physics Group is an established research group specializing in the study of atomic nuclei, in particular nuclei with excessive proton(s) or neutron(s). Our research interest covers nuclear structure, nuclear reaction and nuclear astrophysics.  

Many important results in the energy range of 50 keV - 1 GeV have been achieved at RIBLL1, RIBLL2, ETF, 320-kV platform, LEAF and other facilities around the world. The group undertakes the development of state-of-the-art target systems, and radiation and nuclear detection systems necessary for nuclear-physics experiments, dark-matter research and environmental-radiation measurement on Mars. The group is also responsible for the construction of the new generation in-flight fragment separator of IMP-CAS -- High energy FRagment Separator (HFRS) -- at High Intensity heavy-ion Accelerator Facility (HIAF).  

There are 21 staff members, including 13 senior scientists, and 9 students in the group. The director of the group is Prof. ONG Hooi Jin.
