Study of the Halo Structure for Some Light Neutron-Rich Nuclei Using the Cosh Potential

Abstract

The radial wave functions of the cosh potential within the three-body model of $$\left({\textrm{Core}+2n}\right)$$ have been employed to investigate the ground state properties such as the proton, neutron and matter densities and the associated rms radii of neutron-rich $${}^{{6}}$$ He, $${}^{{11}}$$ Li, $${}^{{14}}$$ Be, and $${}^{{17}}$$ B exotic nuclei. The density distributions of the core and two valence (halo) neutrons are described by the radial wave functions of the cosh potential. The obtained results provide the halo structure of the above exotic nuclei. Elastic electron scattering form factors of these halo nuclei are studied by the plane-wave Born approximation.
