Abstract

We study how EFT can improve the description of reactions used to study the structure of exotic nuclei. Using Halo EFT helps constraining the potential that simulates the interaction between the projectile constituents. It enables us to include ab initio results within the reaction model and to clearly identify the nuclear properties probed by the reaction. New local chiral EFT nucleon-nucleon interactions can also be used to derive nucleus-nucleus optical potentials from first principles, which can provide reliable inputs in reaction modelling.

Highlights

Halo nuclei have been discovered thanks to the development of radioactive-ion beams in the mid-80s [1]
We explore how effective field theory (EFT) can help us build a realistic few-body description of 11Be from the ab initio calculation of Calci et al [2] and how it could help us derive the optical potentials needed as inputs for the reaction model from first principles
After a quick presentation of the reaction model we consider in this study, we present in Sec. 3 how the ab initio results are described within the Halo EFT

Summary

Introduction

Halo nuclei have been discovered thanks to the development of radioactive-ion beams in the mid-80s [1]. New local chiral EFT nucleon-nucleon interactions can be used to derive nucleus-nucleus optical potentials from first principles, which can provide reliable inputs in reaction modelling. We explore how effective field theory (EFT) can help us build a realistic few-body description of 11Be from the ab initio calculation of Calci et al [2] and how it could help us derive the optical potentials needed as inputs for the reaction model from first principles.
