Electric Properties of the Neon-31 Nuclei Under Halo EFT Formalism

Abstract

The electric properties of the $$^{31}\hbox {Ne}$$ halo system is studied using Halo Effective Field Theory. We apply the Effective-Range method to match the parameters of the EFT from obtained data on the $$1/2^{+}$$ and $$3/2^{-}$$ levels in Neon-31 nuclide. We then obtain predictions for the one-neutron separation energy for the ground $$3/2^-$$ state and the predicted $$1/2^+$$ state. It is shown that the $$^{31}\hbox {Ne}$$ has a halo feature with a small separation energy. The neutron radius is also discussed in this paper. Our work provides an applicable approach to analyze nuclei with heavy mass and large deformation.
