• Resumen

  • Using different potentials based on phenomenological, semi microscopic, and microscopic models, we investigated the reaction dynamics induced by the weakly bound ^(6)Li ions on a heavy mass target ^(208)Pb at sixteen energy sets ranging from 25 MeV to 210 MeV. The ^(6)Li cluster nature and its dissociation into a core (α-particle) and a valence particle (deuteron) orbiting this core was taken into consideration using the cluster folding model (CFM). The new version of Sao Paulo potential (SPP2) is also used to investigate ^(6)Li+^(208)Pb data. In order toreproduce the experimental data, the strength of real part of potential created using SPP and CFM should be reduced by ∼ 49 % and 62 %, respectively. The data could be well reproduced using non-renormalized real cluster folding potential, if an additional dynamical polarization potential (DPP) of repulsive real surface form is introduced. The observed reduction in the strength of the real double folded and cluster folding potentials is due to the break-up effect of ^(6)Li.
