Experimental nuclear physics is one of the top research activities at the Ruđer Bošković Institute (RBI), the largest Croatian research center in science and applications. The RBI nuclear physics group has strong link with the research group at the University of Zagreb (UoZ). RBI scientists perform experiments at the RBI Tandem accelerator facility and at the top EU experimental facilities in collaboration with the prominent EU research groups in the field, including partners from the Laboratori Nazionali del Sud INFN (INFN-LNS), Catania, Italy and the Nuclear Physics Group from the University of Birmingham (UoB), UK. With this project we propose to strengthen scientific relationships, the exchange of know-how and sharing of experience between RBI, UoZ, INFN-LNS and UoB partners in the research field of our mutual interest, focusing on the studies of nuclear molecules and other areas at the forefront of research for new phenomena in nuclear physics. This will be achieved by: (i) reinforcement of RBI experimental capabilities through the upgrade of the local experimental facility, (ii) exchange of personnel between partner institutions, hiring and training of young staff at accelerator facilities, (iii) organization of workshops. Upgraded research infrastructure for low energy measurements at RBI and complementary facility at INFN-LNS for intermediate energy measurements through this partnership would increase research opportunities for even broader European experimental nuclear physics community.
