Abstract: Based on the systematic investigation of the data available, a Z 1/3 law for nuclear charge radii is shown to be superior than the generally accepted A1/3 law. The Z1/3 law describes data very well for the nuclei close to the β-stability line, while an approximate linear dependence of isospin must be added when it is applied to the nuclei far from the β-stability line. A new isospin dependence Z1/3 formula thus obtained is proved to be more effective to describe the charge radii data. The collective behavior of the light and heavy nuclei has been discussed.
