Considering non-locality in the optical potentials within eikonal models

Reactions at high energies (E>100A MeV), such as breakup and knockout, are often used to probe the structure of nuclei away from stability. The key ingredient of any reaction analyses are the effective interactions between the clusters, known as the optical potentials. Such potentials are intrinsically non-local, and their non-locality affects significantly reactions observables. In this talk, I will start by presenting the effects of non-locality in the optical potentials for transfer observables at E>100A MeV. Our analysis shows that these reaction observables are significantly impacted by non-locality in the optical potentials. Since knockout reactions are dominated by stripping (transfer to inelastic channels), non-locality is expected to have a large effect on knockout observables too. In the energy regime of breakup and knockout, the eikonal approximation is the tool of choice to interpret these reactions because of its simplicity. In the second part of this talk, I will discuss different avenues for extending the eikonal method to include non-local interactions.
