Description of 31Ne in Halo EFT — •Wael Elkamhawy1 and Hans-Werner Hammer1,21IKP, TU Darmstadt — 2EMMI, GSI Helmholtzzentrum für Schwerionenforschung GmbH

Previous investigations of 31Ne via 1n-removal reactions on C and Pb targets revealed that it is a deformed nucleus with a significant P-wave halo component. We construct a P-wave Halo EFT for 31Ne in order to provide an appropriate framework for its description. Thereby, we use a spherical Halo EFT that is ideally suited to describe the properties of halo nuclei beyond S-waves.

Within this framework, we calculate electromagnetic properties such as the form factors and extract the different multipole moments and the corresponding radii. Since the low-energy observables appear explicitly within Halo EFT, we are able to establish universal correlations between them. Moreover, we consider the photodisintegration of 31Ne into the continuum and determine the differential B(E1) transition strength which in practice is measured using Coulomb excitation of the 31Ne nucleus.
