Abstract
We investigate heavy-ion multinucleon transfer reactions using the coupled-channels formalism. We first use the semiclassical approximation and show that a direct coupling between the entrance and the pair transfer channels improves a fit to the experimental one- and two-neutron transfer cross sections for the and systems. We then discuss the validity of the perturbative approach and highlight the effect of high-order terms. The effect of absorption is also investigated for energies around the Coulomb barrier. Finally, we use a quantal coupled-channels approach to achieve a simultaneous description of the fusion cross sections and the transfer probabilities for the reaction. We find a significant effect of the couplings to the collective excited states on the transfer probabilities around the Coulomb barrier.
