Investigation of exotic nuklei reactions by using the optical model and coupled channels model

In this study exotic properties of the 6He and 11Be nucleus are described. For this reason the scattering of 6He and 11Be with various nucleus were investigated. In order to determine depth of the real and the imaginary parts of the potential, two equations have been introduced. Both phenomenological and double folding methods with 2 parameter Fermi density distribution have been quite successful in explaning the exprimental data for 6He nuclei. However, in the case of 11Be, both methods were inadequate in explaining the experimental data. The result of the coupled-channels method provided better agreement. In addition the coupled channels method described the data for 11Be very successful when the deformations were taken.
