Heavy-ion fusion cross sections and barrier distributions for 12C, 16O, 28Si and 35Cl on 92Zr

The fusion excitation functions and barrier distributions for the fusion of 12C, 16O, 28Si and 35Cl on 92Zr have been calculated using one-dimensional barrier penetration model, taking scattering potential as the sum of Coulomb and proximity potential. Calculated results are compared with experimental data and CC calculations using code CCFULL. 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 give good fit. Reduced reaction cross sections for the systems have also been described
