Megjegyzések:	The smooth N and Z dependence of nuclear rms charge radii is interpreted by a two-liquid drop model with ?p + ?n = ?0 = const. Proton and neutron radii Rp and Rn are given in closed form. In addition to rms charge radii, the model yields the nucleon number dependence of the skin thickness ,s, e.g.ds = 0.00124 ? dA for Sn isotopes, in agreement with experimental results and theoretical calculations. A strong correlation between the two global parameters of the model ? including sst the skin thickness of the stable isotope? is established. If sst is taken from experiment, the other parameter is also fixed; this parameter (m) characterizes the restoring force responsible for the skin thickness. Its value m=2.2 suggests that ? in addition to the numberof nucleons in the skin ? the skin thickness also influences the distribution of "surplus" nucleons between volume and skin.
