Abstract：
Both theoretical calculations and experimental observations show that there exists proton halo in the first excited state (1/2)⁺ of ¹⁷F. The elastic electron scattering process off the the first excited state of ¹⁷F is studied with the RMF model and Eikonal approximation. The charge form factor is calculated and compared with those of ¹⁶O and ¹⁶F. The results show that the existence of the proton halo can lead to an obvious change to the form factors in the range of low and moderate-momentum transfer. This indicates that elastic electron-nucleus scattering can be an effective tool for a refined study of the proton-halo structure of the proton-rich nuclei.
