Fusion cross sections are extracted for the (7)Li + (28)Si system, via reaction cross section and transfer measurements at sub- and near-barrier energies (E(lab) = 5.7 to 14 MeV). The energy evolution of transfer to reaction cross section ratios is determined with the aid of CDCC calculations, which subsequently allows the deduction of fusion cross sections at sub- and near-barrier energies. It is shown that fusion can be well represented in a BPM context. Fusion cross sections are compared for the systems (7)Li + (28)Si and (6)Li + (28)Si, the latter studied previously, and are found to exhibit different strengths. Last, the direct channels determined at 13 MeV, are found to be dominated by a 2n-transfer mechanism.
