Fusion-fission cross sections for S32+138Ba and Ti48+122Sn at near-barrier energies

The fission cross sections for S32+138Ba and Ti48+122Sn in the regoin of the fusion barrier have been measured. These results are combined with evaporation residue cross sections from another measurement to obtain the total fusion excitation functions for these systems at energies near and below the barrier. Coupled channels calculations easily reproduce the experimental results.
