Abstract

The influence of the dissipation due to transfer processes on the quasielastic barrier distributions of the ²⁰Ne+^92,94,9BMo systems was investigated at the Heavy Ion Laboratory, University of Warsaw. Differential transfer cross sections were measured at four beam energies (66-73 MeV) around the Coulomb barrier. For the ⁹²Mo target, the measurements indicate no significant variation in the transfer channels across the beam energy range. In contrast, for the ^94,9BMo isotopes, additional one- and two-neutron pickup reactions appear at lower energies. These preliminary results suggest that transfer reactions may influence to the shape of quasielastic barrier distributions in heavier Mo isotopes. Further analysis and theoretical developments, including an upgrade of the CCFUL-sc code to explicitly include the energy dependence of transfer couplings, are underway to better quantify this effect.
