Charge form factors of exotic nuclei in deformed Hartree–Fock–Bogolyubov calculations

Abstract

With the development of electron scattering experiments off exotic nuclei, many theoretical researches have been devoted to investigate the nuclear charge form factors recently. In this paper, we extend the studies of electron scattering by combing the deformed Hartree–Fock–Bogolyubov (HFB) model and the distorted wave Born approximation (DWBA) method. Comparing the theoretical with the experimental data, the validity of the deformed HFB model to describe the nuclear density distributions can be verified for both the spherical and deformed nuclei. By further investigating the of the isotopic chain, the effects of the nuclear deformation on the changing trends of of isotopes are provided. For even–even Xe isotopes, the nuclear deformation can influence the positions of the diffraction minima of . For odd-A Cs isotopes, the nuclear deformation can affect the values of diffraction minima of . The studies in this paper can offer useful guidances for the coming electron scattering experiments on unstable nuclei.
