Abstract.Using the experimental occupation probabilities for the single particle states near the Fermi surface, the charge distribution of 54Fe, 5s-6~Ni and 64"66Zn have been calculated on the basis of an optimized one body potential. Excellent agreement with the experimental values have been found both in the case of single particle (-hole) energies and rms charge radii of the nuclei under consideration. Calculated values of Barrett moments and equivalent radii are in good agreement with the experiment. The details of the charge distributions have been evaluated by Fourier-Bessel analysis.
