Heavy-ion fusion near the Coulomb barrier attract experimental and theoretical interest. The collisons are typically characterized by the presence of many open reaction channels. In the energies around the Coulomb barrier, the processes are elastic scattering, inelastic excitations and fusion operations of one or two nuclei. The fusion process is defined as the effect of one-dimensional barrier penetration model, taking scattering potential as the sum of Coulomb and proximity potential. We have performed heay-ion fusion reactions with coupled-channels (CC) calculations. CC formalism is carried out under barrier energy in heavy- ion fusion reactions. In this work fusion cross sections have been calculated and analyzed in detail for the three systems in the framework of CC approach (using the codes CCFULL[16], CCFUS [17] and CCDEF [18]) . Calculated results are compared with experimental data, including excitation of the projectile and target to the lowestand states and with the datas computed from ‘nrv’. CCDEF, CCFULL and ‘nrv’ explains the fusion reactions of heavy-ions very well. There is a good agreement between the calculated results with the experimental and nrv results [19].
