Investigation of exotic nuclei by three-body approach

Due to the different structure of exotic nuclei, it has an important role in nuclear physics in the last 30 years. Experimental and theoretical studies provided knowledge about basic and different structure of exotic nuclei. Thus in this thesis, the interaction between different target nuclei with 11Be and 17F exotic nuclei were analysed by using different methods. In this thesis, the interaction between 64Zn, 120Sn and 209Bi target nuclei with 11Be exotic nuclei was investigated. 11Be + 64Zn system in the energy 25.4 MeV, 11Be +120Sn system in the energy 32 MeV and 11Be + 209Bi system in energies 40-48 MeV was examined. These systems was analysed using Optical Model, Coupled Channels Model and Cluster Model. Angular distribution of cross section was examined. The obtained results were compared with experimental data. In the energies 90.4 MeV, 98 MeV and 170 MeV, the interaction between 208Pb target nuclei with 17F nuclei was examined. 17F + 208Pb system was analysed using double Folding model and CDCC (Continuum Discretized Coupled Channels). The real part of the core-target potential was determined in two different ways using microscopic double folding method and phenomenological method.
