Break-up effect of the weakly bound 6Li ions scattered by 208Pb target

Using different potentials based on phenomenological, semi microscopic, and microscopic models, we investigated the reaction dynamics induced by the weakly bound Li-6 ions on a heavy mass target Pb-208 at sixteen energy sets ranging from 25 MeV to 210 MeV. The Li-6 cluster nature and its dissociation into a core (alpha-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 Li-6+Pb-208 data. In order to reproduce the experimental data, the strength of real part of potential created using SPP and CFM should be reduced by similar to 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( )6L.

Automated summary

This research investigated reaction dynamics of Li-6 ions on Pb-208 target using different potentials, finding that the strength of SPP and CFM potentials needs to be reduced to reproduce experimental data, and introducing a dynamic polarization potential to explain the observed reduction in potential strength.
