The effect of the coupled channel on the calculations of the total fusion reactions cross section fus and the fusion barrier
distribution d 2 E dE2 fus have been studied for the reactions involving heavy ions nuclei for the systems 16O on 144,154Sm. The effect
of double, octupole and quadrupole phonon excitations in144Sm were considered and rotational deformation were included for the
nucleus 154Sm with ground state rotational band up-to the 4+ states. The calculated fusion reactions cross section fus and the fusion
barrier distribution d 2 E dE2 fus are compared with the available experimental with and without the inclusion of the coupled
channels effects. The inclusion of the coupled channel in the calculations enhances the fusion cross section below the Coulomb and
brings the calculated fusion reaction cross section near to the experimental data.
