“…11 the variation of the charge and matter rms radii with the relative neutron excess for all isotopic chains considered. The use of LSSM charge densities for He and Li isotopes [32,41] leads to a small decrease of the charge rms radius R ch from 4 He to 6 He and 8 He and to a larger decrease of R ch from 6 Li to 11 Li. On the contrary, the behavior of the charge radii for heavier Ni, Kr, and Sn isotopes shows a smooth increase of R ch with increase of the neutron number, while the nuclear matter radii for these isotopes increase faster.…”

Charge and matter distributions and form factors of light, medium, and heavy neutron-rich nuclei

et al. 2005

Results of charge form factors calculations for several unstable neutron-rich isotopes of light, medium, and heavy nuclei (He, Li, Ni, Kr, Sn) are presented and compared to those of stable isotopes in the same isotopic chain. For the lighter isotopes (He and Li) the proton and neutron densities are obtained within a microscopic large-scale shell-model, while for heavier ones Ni, Kr, and Sn the densities are calculated in deformed self-consistent mean-field Skyrme HF+BCS method. We also compare proton densities to matter densities together with their rms radii and diffuseness parameter values. Whenever possible comparison of form factors, densities and rms radii with available experimental data is also performed. Calculations of form factors are carried out both in plane wave Born approximation (PWBA) and in distorted wave Born approximation (DWBA). These form factors are suggested as predictions for the future experiments on the electron-radioactive beam colliders where the effect of the neutron halo or skin on the proton distributions in exotic nuclei is planned to be studied and thereby the various theoretical models of exotic nuclei will be tested.
