The fusion excitation functions for the fusion of 32 S on 90,96 Zr have been calculated larger value, while using one-dimensional barrier penetration model, taking scattering potential as the sum of Coulomb and proximity potential and the calculated values are compared with experimental data with considerations to shape degrees of freedom. At and above the barrier the computed cross sections match well with the experimental data, whereas below the barrier, calculations with nuclear surface tension coefficient improved by Reisdorf in the proximity potential with considerations to shape degrees of freedom give an approximate fit. Reduced reaction cross sections for the systems 32 S on 90,96 Zr have also been described.
