The Radioactive Ion Beam Physics Group is dedicated to the study of atomic nuclei, with a specific focus on exotic nuclei featuring extreme proton-to-neutron ratios. Our research interests span nuclear structure, reaction dynamics, and nuclear astrophysics.

The group is responsible for the operation of the HIgh-rigidity Radioactive Ion Beam Line (HIRIBL) as well as the First and Second Radioactive Ion Beam Lines in Lanzhou (RIBLL1 and RIBLL2).

The group currently has 18 staff members, including 7 senior scientists. The director of the group is WANG Shitao.

1. Study of structure and reaction of exotic nuclei by using intermediate- and high-energy radioactive ion beams.

2. Development of detector systems for charged particles, gamma rays, and neutrons.
