The nuclear and Coulomb breakup of the weakly bound $^{6}$Li with targets in the range from A = 59 to 208

TL;DR

This study uses CDCC calculations to analyze nuclear and Coulomb breakup of weakly bound $^{6}$Li on various targets, revealing how breakup mechanisms depend on target properties and comparing predictions with experimental fusion data.

Contribution

It provides a systematic analysis of nuclear and Coulomb breakup contributions across different target masses using CDCC, highlighting the relative importance and scaling behaviors.

Findings

Nuclear breakup is more significant for lighter targets but not overwhelmingly so.

Good agreement between calculations and experimental elastic scattering data.

Predicted total breakup cross sections are compared with fusion cross sections at similar energies.

Abstract

We have performed CDCC calculations for the $^{6}$Li + $^{59}$Co, $^{144}$Sm and $^{208}$Pb systems, to investigate the dependence of the relative importance of nuclear and Coulomb breakup on the target charge (mass) at near barrier energies. The calculations were in good agreement with the experimental elastic scattering angular distributions for these systems and then, their predictions to the nuclear, Coulomb and total breakup were investigated. Although the relative importance of the nuclear breakup is, as expected, larger for lighter targets, this effect is not very pronounced. We also investigate a scaling of the nuclear breakup with the target mass and we compare the predictions for the integrated total breakup cross sections with experimental fusion cross sections at similar energies.
