摘要：

Charge radius and charge form factors of different charge density distributions for He-6,He-8 are calculated with the relativistic Eikonal approximation. Detailed comparisons and discussions are presented. It is found that the charge form factors curves of He-6,He-8 axe much lower than the experimental ones of 4 He. This is, in principle, consistent with the experimental fact. Whereas detailed comparison among the charge form factors which correspond to different charge distributions show significant deviations. This indicates that the effects of the, correlations between the halo neutrons and the alpha-core in He-6,He-8 with different charge density distributions are quite different. This result would provide a useful reference for the possible experiments on the next-generation electron-nucleus collider and for the tests of different theoretical models for the exotic nuclei He-6,He-8.
