Abstract:The progress of RIB studies is briefly introduced. The prospects are discussed in china. Based on the few RIB setup operated, a cooling storage ring under construction and a ISOL type facility proposed, it is mentioned as follow:①the structure of nuclei extending to the boundary of bound nuclei, especially for super heavy elements.②the studies of fundamental interactions and symmetries exploited by RIB. ③ nuclear astrophysics emphasis on the processes of element synthesis include nuclear capture reactions and decay with unstable nuclei.④the applications main for material, biology, medicine and et al.
