Systematical study of optical potential strengths in reactions involving strongly, weakly bound and exotic nuclei on $^{120}$Sn

TL;DR

This study systematically analyzes optical potential strengths in elastic scattering reactions involving various weakly bound and exotic nuclei on $^{120}$Sn, using experimental data and the Sao Paulo Potential to understand nuclear interactions.

Contribution

It provides a comprehensive systematic analysis of optical potential strengths across multiple reactions with weakly bound and exotic nuclei, using the double-folding Sao Paulo Potential.

Findings

Optical model fits are sensitive to nuclear matter density models.

Variations in optical potential strengths significantly affect scattering data fits.

The systematic approach helps understand nuclear interaction mechanisms.

Abstract

We present new experimental angular distributions for the elastic scattering of $^6$Li$+^{120}$Sn at three bombarding energies. We include these data in a wide systematic involving the elastic scattering of $^{4,6}$He, $^7$Li, $^9$Be, $^{10}$B and $^{16,18}$O projectiles on the same target at energies around the respective Coulomb barriers. Considering this data set, we report on optical model analyses based on the double-folding Sao Paulo Potential. Within this approach, we study the sensitivity of the data fit to different models for the nuclear matter densities and to variations in the optical potential strengths.
