Shell model and Hartree-Fock calculations for some exotic nuclei

Mass density distributions, the associated nuclear radii and elastic electron scattering form factors of light exotic nuclei, Li-11, Be-11, Be-14 and B-8 have been calculated using shell model (SM) and Hartree-Fock (HF) methods. We consider truncated spsdpf no core SM and WBP two-body effective interaction to give the SM wave functions. The single-particle matrix elements have been calculated with Skyrme-Hartree-Fock (SHF) potential with different parametrizations. It is shown that the calculated densities and form factors are in fine agreement with experimental data. This agreement can be interpreted as the adequacy of the HF mean-field approximation for exotic nuclei.
