“…In these tables we also show the results of the measured fission cross sections for the systems S + Ba and Ti + Sn [18]. The values of the fission cross sec- tion for the system Si + Ce were not measured, but the expectation of a reliable statistical model calculation, as discussed below, indicates that fission is negligible for this system for all energies studied here, except for the two higher ones.…”

ln an efFort to study the efFect of the entrance channel mass asymmetry on the fusion process at near-barrier energies, we have measured the fusion cross section and its distribution according to the difFerent evaporation residues for the Si + Ce, S + Ba, and Ti + Sn systems. All these systems lead to the same compound nucleusHf. The measurements were performed using a delayed x ray technique. For the last two systems we have also measured the fission cross sections in the same bombarding energy range. This experimental information can be used to restrict the free parameters of the statistical model used to account for the relative yield. A constrained and realistic statistical decay model is useful in reducing the uncertainties in the determination of the spin distribution from measurements of gamma multiplicities for these systems. The excitation function for the fusion cross section can be described using a schematic coupled channels calculation with realistic coupling strengths. Our results show no unambiguous eKect that can be associated with the entrance channel mass asymmetry .PACS number(s): 25.70. Jj, 24. 10.Eq
