Investigation of cross sections and barrier distribution functions in heavy-ion fusion reactions by coupled channel method

In this study, heavy ion fusion reactions were investigated systematically for 48 reaction by coupled channel method. Heay- ion fusion near the Coulomb barrier is of interest to experimenters and theorists. Collisions are typically characterized by the presence of many open reaction channels. In the energies around the Coulomb barrier, the process is the elastic scattering of one or two nuclei, inelastic excitations and fusion operations. The fusion process is defined as the effect of a one-dimensional barrier penetration model that takes scattering potential as the sum of Coulomb and proximity potential. In this study, fusion cross sections were examined in detail by using CC calculations, such as CCFULL, CCDEF, CCFUS and NRV codes and Wong formalism with 2^+and 3^(- ) excitation for incoming particle and target . The calculated fusion cross section results were compared with the experimental data. It was determined that CCFULL and CCDEF, produced more reliable data than CCFUS. The barrier distributions for all reactions were calculated by CCFULL and NRV codes under coupling values and by Wong formalism. The harmony between these calculations was examined and the models were found to be in harmony with each other.
