Charge form factors corresponding to proton density distributions in exotic nuclei, such as 6,8 He, 11 Li, 17,19 B and 14 Be are calculated and compared. The results can be used as tests of various theoretical models for the exotic nuclei structure in possible future experiments using a colliding electron-exotic nucleus storage ring. The result of such a comparison would show the effect of the neutron halo or skin on the proton distributions in exotic nuclei.

“…That is why it is necessary to consider also other more realistic theoretical predictions for the densities of the helium isotopes. We use also the proton densities of 4,6,8 He obtained within the LSSM calculations in a complete 4hω shell-model space [26]. In them Woods-Saxon single-particle (s.p.)…”

“…Nowadays, a substantial amount of experimental data exists for the cross sections of 6 He+p elastic scattering at different energies. For example, proton elastic scattering angular distributions were measured at incident energies less than 100 MeV/N for 6 He, namely 25.2 [1,2,3,4], 38.3 [5], 41.6 [6,7,8], and 71 MeV/N [9,10] and at energy of 700 MeV/N for He and Li isotopes (e.g. refs.…”

Abstract. Calculations of microscopic optical potentials (OP's) (their real and imaginary parts) are performed to analyze the 6 He+p elastic scattering data at a few tens of MeV/nucleon (MeV/N). The OP's and the cross sections are calculated using three model densities of 6 He. Effects of the regularization of the NN forces and their dependence on nuclear density are investigated. Also, the role of the spin-orbit terms and of the non-linearity in the calculations of the OP's, as well as effects of their renormalization are studied. The sensitivity of the cross sections to the nuclear densities was tested and one of them that gives a better agreement with the data was chosen.

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

et al. 2005

View full text Add to dashboard Cite

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.
