Elastic Electron Scattering from Some Proton-Rich Exotic Nuclei

The ground-state properties such as the neutron, proton and matter densities and the associated rms radii of proton-rich 8B and 17Ne halo nuclei are calculated using single-particle radial wave functions of Woods-Saxon (WS) potential. It found that the structure of the halo proton in 8B is a pure (1p1/2) and the structure of the two halo protons in 17Ne is mixed configurations with dominant (2s1/2) 2. Elastic electron scattering form factors of these halo nuclei are also studied by the plane wave Born approximation. Effects of the long tail behavior of the charge density distribution on the charge form factors of 8B and 17Ne are analyzed. It is found that the difference between the charge form factor of 8B and that of stable isotope 10B (or of 17Ne and that of stable isotope 20Ne) is attributed to the influence of the charge density distributions of the last proton in 8B (or of the last two protons in 17Ne).
