Abstract

In this study by Using the di-nuclear systems model (DNS), the evaporation residue cross-section of two cold fusion reactions 64Ni+208Pb and 64Ni+209Bi is calculated. ،The nuclear proximity potential is used for interaction between nuclei. In these calculations thermodynamic quantities of compound nuclei such as temperature and heat capacity are obtained using Ginzburg- Landau (EGL) theory and temperature dependent back shifted Fermi gas model (TDP- BSFGM). The obtained results of cross section are compared with experimental data and other data that is obtained using another model. Also, the plot of heat capacity versus temperature has a S-shape form which is indicator of breaking of the nucleonic pairs.
