Theoretical study on neutron distribution of ²⁰⁸Pb by parity-violating electron scattering

【摘要】 The precise determination of neutron distribution has important implications for both nuclear structure and nuclear astrophysics. The purpose of this paper is to study the characteristics of neutron distribution of²⁰⁸ Pb by parity-violating electron scattering（PVS）. Parity-violating asymmetries of²⁰⁸ 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.更多还原
