Abstract
The nuclear charge density distributions, form factors andcorresponding proton, charge, neutron, and matter root mean squareradii for stable 4He, 12C, and 16O nuclei have been calculated usingsingle-particle radial wave functions of Woods-Saxon potential andharmonic-oscillator potential for comparison. The calculations for theground charge density distributions using the Woods-Saxon potentialshow good agreement with experimental data for 4He nucleus whilethe results for 12C and 16O nuclei are better in harmonic-oscillatorpotential. The calculated elastic charge form factors in Woods-Saxonpotential are better than the results of harmonic-oscillator potential.Finally, the calculated root mean square radii usingWoods-Saxonpotentials how overestimation in comparison with experimental dataon contrary to the results of harmonic-oscillator potential.

Summary
The radial distributions and sizes of nuclear matter and charges are basic properties of nuclei. The harmonic-oscillator (HO) potential is not accurate to describe the nuclear central confining potential because the potential continues to give a contribution even for much larger (distance from the center of nucleus) and does not become zero, besides the radial wave functions obtained from HO have a Gaussian fall-off behavior at large r which does not reproduce the correct exponential tail. Gamba et al [4] calculated the parameters of a WS potential well for ten p-shell nuclei by fitting the electron scattering form factors and single-particle separation energies
