“…In Fig. 17(b), we see that the value of σ 2 remains almost constant between 22 8 O and 28 14 Si when mainly the 1d 5/2 shell is being filled. From 30 16 S on, the 2s 1/2 and 1d 3/2 levels start to be appreciably occupied and σ 2 starts increasing almost linearly with A until the proton-drip-line nucleus 34 20 Ca.…”

“…The N = 82 isotones below 132 Sn are believed to be in close relation with the peak of the solar r-process abundance distribution observed around the mass number A = 130 [43,44], whereas the N = 50 isotones near 78 Ni are thought to be responsible for producing the pronounced abundance peak observed around A = 80 [43,45]. On the other hand, scattering data for light nuclei, such as those of N = 14, are likely to be obtained in future electron scattering facilities such as SCRIT [19][20][21] and ELISe [22,23].…”

“…Experimentally, the investigation is more difficult because of the limitations arising from small production rates, short half-lives, and small cross sections when one deals with unstable nuclei [13,[16][17][18][19][20][21][22][23].…”

“…It is to be mentioned that a mean-field treatment is not expected to be sufficient for light exotic nuclei [27]. Thus, the N = 14 isotonic chain studied below (with nuclei from 22 O to 34 Ca) corresponds to a somewhat limiting case, and the mean-field results should be taken as semiquantitative. The calculations with the G2 model predict a relatively magic character of the neutron numbers N = 14 and N = 16.…”

“…For this purpose, a new generation of electron-RIB colliders using storage rings is under construction at RIKEN (Japan) [13,16] and at GSI (Germany) [17,18]. It is expected that * xavier.roca.maza@mi.infn.it in the near future the Self-Confining Radioactive Nuclei Ion Target (SCRIT) project in Japan [19][20][21] and the electron-ion scattering in the storage ring (ELISe) experiment at FAIR in Germany [22,23] will offer the opportunity to study the structure of unstable exotic nuclei by means of electron scattering.…”

Electron scattering on unstable nuclei is planned in future facilities of the GSI and RIKEN upgrades. Motivated by this fact, we study theoretical predictions for elastic electron scattering in the N = 82, N = 50, and N = 14 isotonic chains from very proton-deficient to very proton-rich isotones. We compute the scattering observables by performing Dirac partial-wave calculations. The charge density of the nucleus is obtained with a covariant nuclear mean-field model that accounts for the low-energy electromagnetic structure of the nucleon. For the discussion of the dependence of scattering observables at low-momentum transfer on the gross properties of the charge density, we fit Helm model distributions to the self-consistent mean-field densities. We find that the changes shown by the electric charge form factor along each isotonic chain are strongly correlated with the underlying proton shell structure of the isotones. We conclude that elastic electron scattering experiments on isotones can provide valuable information about the filling order and occupation of the single-particle levels of protons.

The ELISe project, which is an integral part of the development of FAIR -Facility for Antiproton and IonResearch (FAIR, Darmstadt, Germany), is a project for developing the first accelerator in the world with colliding beams that uses the latest accelerator technology and experimental techniques. The ELISe experimental facility makes it possible to conduct a wide class of experiments using different nuclear reactions and thereby to study the diverse problems of nuclear physics and nuclear reactions. The experiments on electron scattering by nuclei far from the valley of stability will yield unique information on the distribution of charge in nuclei and the transitional density in nuclear excitations as well as single particle and cluster systems.Experiments with electron scattering by atomic nuclei have opened up large possibilities for studying the size and shape nuclei and internal nuclear dynamics [1]. However, up to now such studies have been limited to stable and long-lived isotopes. A theoretical analysis of electron scattering by exotic nuclei performed in recent years indicates that this method can be extended to nuclei far from the valley of stability [2][3][4][5][6][7]. The objective of the ELISe project is to apply this method to the study of unstable nuclei. The ELISe facilities will be a unique tool for making precise measurements of the distribution of the charge density and obtaining information on the shell structure and internal dynamics of exotic nuclei and on the mechanism of excitation of collective nuclear transitions in them. The experiments will make an enormous contribution to the diversity of high-quality data on nuclear matter that will become accessible in FAIR.The first technical proposal concerning a colliding beam accelerator complex was made at the Joint Institute for Nuclear Research (OIYaI) [8]. The ideas proposed were subsequently developed and included in the plan of the rare-isotope beam factory RKEN (Japan) as the MUSES project [9] and in the FAIR program as the ELISe project (Germany) [10][11][12]. However, neither project has been implemented thus far. During the coming years, a unique facility where electrons are scattered by exotic nuclei could appear in the ELISe project.Thirty-five institutes from 12 countries are participating in the ELISe project.
