Influences of the change of neutron number on the charge form factors of Ca and Ni isotopes
We calculate the charge form factors of the even-even isotopes on the Z=20 and 28 isotopic chains,including both the stable nuclei and unstable ones,and investigate the influences of the change of neutron number on the charge form factors of the Ca and Ni isotopes systematically with the relativistic eikonal approximation associated with the self-consistent relativistic mean field model.We find that the charge form factor changes significantly and regularly with the variation of neutron number.The charge form factors shift outward and downward as the nucleus moves from the very neutron-rich region to the very proton-rich region along an isotopic chain.The significant shift shows that the charge form factor is very sensitive to a change of neutron number.The regularity of the variation of the charge form factors along an isotope chain may suggest certain laws which rules the influence of the neutrons on the distribution of the protons.The calculations will provide a useful reference for the future experiments as well as a test of the reliability of the relativistic mean field model for unstable nuclei far from the stability line.
