| Abstract: | Relativistic mean-field theory and phase-shift analysis are combined together to investigate the elastic Coulomb scattering between electrons and unstable nuclei. Electron scattering at several different energies is studied and compared, in order to see the energy dependence of electron-nucleus scattering. It is shown that electron scattering at 200 MeV or 300 MeV can be used to reveal electron-nucleus scattering information around the first diffraction minimum. Shifts in opposite directions are obtained for the first diffraction minima of the electron scattering off the ground and first excited states of 17F with 16O as reference, and similar effects are obtained for 18Ne. Besides, some neutron-rich N=8 isotones are also studied. Results showthat electron scattering will be very useful and important in studying both proton- and neutron-rich nuclei in the future. |
