Microscopic optical potentials including breakup effects for elastic scattering

TL;DR

This paper develops a microscopic optical potential incorporating breakup effects for elastic scattering of weakly-binding nuclei, using the Glauber model and g-matrix folding, and validates it against exact calculations and experimental data.

Contribution

It introduces the eikonal potential derived from the g-matrix folding model, improving the accuracy of breakup effect inclusion in elastic scattering calculations.

Findings

The eikonal potential reproduces results from the continuum-discretized coupled-channels method.

It partially corrects the inaccuracy of the eikonal approximation in the Glauber model.

The potential is applicable to many-body projectiles like $^6$He scattering from $^{12}$C.

Abstract

We construct a microscopic optical potential including breakup effects for elastic scattering of weakly-binding projectiles within the Glauber model, in which a nucleon-nucleus potential is derived by the $g$-matrix folding model. The derived microscopic optical potential is referred to as the eikonal potential. For $d$ scattering, the calculation with the eikonal potential reasonably reproduces the result with an exact calculation estimated by the continuum-discretized coupled-channels method. As the properties of the eikonal potential, the inaccuracy of the eikonal approximation used in the Glauber model is partially excluded. We also analyse the $^6$He scattering from $^{12}$C with the eikonal potential and show its applicability to the scattering with many-body projectiles.
