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.

“…As has been shown in [1,2], the elastic proton-nucleus scattering at intermediate energy in inverse kinematics is an efficient means of studying nuclear matter density distributions in exotic halo nuclei. An analysis of the measured cross sections for small-angular elastic proton-nucleus scattering allows one to determine both the sizes of the nuclear core and the neutron halo.…”

“…An analysis of the measured cross sections for small-angular elastic proton-nucleus scattering allows one to determine both the sizes of the nuclear core and the neutron halo. At the same time, as has been shown in [1], the sensitivity of the cross sections for elastic proton-nucleus scattering is not sufficient for obtaining information on the matter distribution of the nuclear far periphery, which contains small amount of the nuclear matter. The authors of paper [3] discuss the sensitivity of the reaction cross sections (that is of the integrated cross sections for all inelastic processes) to the nuclear density distribution at large distances from the nuclear centre.…”

Abstract:The microscopic cluster model approach has been performed to study the nuclear structure of the lightest and heaviest two-neutron halo nuclei, 6 He and 22 C, respectively. The matter radius and binding energy for the 6 He and 22 C nuclei are calculated and the effect of the core deformation ( 20 C) on the properties of 22 C nuclei is also discussed.Calculations have shown that the microscopic cluster model provides a good description of binding energy as well as matter radius in comparison to experimental data. The fittings of some parameters such as central potential depth, and surface diffuseness value (a) are discussed to find agreement in the results with the available experimental data. The exotic properties of two-neutron halo nuclides 6 He and 22 C such as weak binding energy, abnormal large matter radius, and Borromean system have been confirmed in the present work.
