Fusion processes in collisions of 6Li beams on heavy targets

We discuss a recently introduced model to evaluate complete and incomplete fusion in collisions of weakly bound nuclei. We propose a modification of the imaginary potential to deal with cross sections at energies well below the Coulomb barrier, and discuss the relation between the cross sections provided by a continuum discretized coupled-channel calculation and the ones measured in actual experiments. The new version of the model is used to make predictions of fusion cross sections in collisions of Li-6 with a few heavy targets, and the results are compared to the available data. The overall agreement between theory and experiment is quite good.
