Abstract：
The binding energies and root-mean-square radii of ^26—32S and ^22—28Si are calculated by the relativistic mean-field model with two sets of parameters TM2 and NL-SH. The calculated results are in agreement with the experimental data. The calculated form factors and differential cross sections of electron scattering on ³²S and ²⁸Si by the Eikonal approximation agree with the experimental data. Further calculations on electron scattering of S and Si isotopes are carried out, and the sensitivity of form factors on charge density is discussed. The form factor of electron scattering on unstable nuclei can be accurately measured in the future electron-nucleus collider. The theoretical predictions would be valuable for future experiments.
