Simultaneous calculation of elastic scattering, fusion, and direct cross sections for reactions of weakly-bound projectiles

TL;DR

This paper presents a unified microscopic approach to simultaneously calculate elastic scattering, fusion, and direct reaction cross sections for weakly-bound projectiles, demonstrating good agreement with experimental data.

Contribution

It introduces a method that constructs polarization potentials microscopically from nuclear structure, enabling comprehensive analysis of multiple reaction channels with minimal adjustable parameters.

Findings

Successfully reproduces experimental cross sections for $^{6}$He+$^{209}$Bi.

Applicable to reactions involving weakly-bound and exotic nuclei.

Uses only one adjustable parameter for all channels.

Abstract

Simultaneous analyses are performed for cross section data of elastic scattering, fusion, Coulomb breakup, and other direct yields for the $^{6}$He+$^{209}$Bi system at near-Coulomb-barrier energies. The bare and dynamical polarization potentials are constructed microscopically from the structure of the colliding nuclei and they reproduce all the data well with only one adjustable parameter. This method of calculation can be successfully applied to the reactions of weakly-bound and exotic projectiles with heavy targets.
