We study the charge radii of exotic nuclei through nuclear calculations and isotopic-shift evaluations. The former ones are performed in the framework of the DCM and the BDCM [1] for nuclei with odd and even numbers of valence particles, respectively. These nuclear models take fully into consideration the correlation between valence particles as well as between valence and core particles. We will present the results obtained for the lithium, berilium and uranium isotopes. To check the reliability of the model, we have carried out isotopic-shift calculations by applying the DCM to the electron subspace and calculating the field- and phase-shift, which characterize the isotopic-shift theory, in suitable electronic transitions. Our calculated charge radii of the light isotopes represent our prediction for the experiments presently being performed at GSI [2].
