摘要：

Low-energy collective E1 moments in nuclei from the Ra-Th and Ba-Sm region are analysed within the shell-correction method based on the reflection-asymmetric Woods-Saxon model. Extensive systematics of experimental intrinsic dipole moments are presented. Shell effects on the isovector E1 moment explain local quenchings in E1 strength observed experimentally. It is demonstrated that the inclusion of the neutron-skin contribution to the macroscopic dipole moment is crucial for the understanding of experimental trends.
