We are proposing to investigate halo and cluster structures of unstable proton or neutron rich nuclei by using radioactive ion beams induced reactions. Halo and cluster structure in nuclei are among the most exciting phenomena of current nuclear physics. Some light proton and neutron rich nuclei such as 6He, 8B, 10C, 11Li, 11Be, 12N and 15C, are radioactive, situated far from the stability valley and can exhibit large radial extension and exotic structures, in which the valence nucleons extend outside the binding potential. The possibility of producing radioactive beams out of these short-lived nuclei offers new and unique opportunities for research in the frontier field of nuclear physics. New experimental data on reaction induced by these nuclei can provide stringent tests for nuclear structure and reaction-mechanism models essential for understanding the physics of the cosmos like the stellar nucleosynthesis. Elastic scattering and direct reactions induced by light exotic radioactive beams are very powerful tools to study their properties since it can reveal details of their unusual features such as extended halos and/or neutron skins. The low binding energy and strong cluster configuration in these exotic nuclei would produce a decoupling between the valence particle and the core nucleus, which give rise to an increase of the breakup and/or transfer probability in the total reaction cross section. Understanding this mechanism and the influence of the breakup in the elastic and fusion processes is still a challenge for both theorists and experimentalists. In this Project we are going to investigate reactions induced by 10Be and 10C radioactive beams.
