摘要：

The anomalous behaviour of the charge radii of the isotopic chain of Pb nuclei has been studied in the relativistic mean-field theory. It has been shown that the relativistic mean field provides an excellent description of the anomalous kink in the isotopic shifts about 208Pb. This contrasts strongly from the Skyrme mean field, where the density-dependent Skyrme forces fail to reproduce the observed trend in the empirical data on the charge radii. The results have been discussed in the perspective of differences in the ansatze of the relativistic and the Skyrme mean-field theories.
