    Abstract

    Excitation functions for quasi-elastic scattering have been measured at backward angles for the systems 32,34S + 197Au and 32,34S + 208Pb for energies spanning the Coulomb barrier. Representative distributions, sensitive to the low energy part of the fusion barrier distribution, have been extracted from the data. For the fusion reactions of 32,34S with 197Au couplings related to the nuclear structure of 197Au appear to be dominant in shaping the low energy part of the barrier distribution. For the system 32S + 208Pb the barrier distribution is broader and extends further to lower energies, than in the case of 34S + 208Pb. This is consistent with the interpretation that the neutron pick-up channels are energetically more favoured in the 32S induced reaction and therefore couple more strongly to the relative motion. It may also be due to the increased collectivity of 32S, when compared with 34S.
