The purpose of this paper is to study the characteristics of neutron distribution of^208 Pb by parity-violating electron scattering（PVS）. Parity-violating asymmetries of^208 Pb with different types of neutron skins are systematically calculated and compared with the experimental data of PREx. The results indicate that the PVS experiments are very sensitive to the nuclear neutron distributions. From further PVS measurements, detailed information on nuclear neutron distributions can be extracted.展开更多

The corrections are calculated including the nucleon and △（1232） intermediate states. And the numerical results are also compared with the recent results reported by other group and other methods.展开更多

The matrix elements of the △j=0 parity-violating electric dipole transitionsand nonvanishing electric dipole moments are discussed and a possible new approach to thesearch for dyons in bound conditions is proposed.展开更多
