核子电磁形状因子

摘要

核子电磁形状因子对于揭示核子内部电荷和磁矩的分布有重要意义，通过 Rosenbluth 散射和极化转移散射理论，介绍了电磁形状因子的两种测量方法及测量结果，同时讨论了两种测量结果存在的差异。%Nucleon electromagnetic form factor plays an important role in revealing the internal distribution of charge and magnetic moment.Through Rosenbluth scattering and polarization transfer scattering theory,two types of measure-ment methods and measurement results of electromagnetic form factors are introduced.Meanwhile the difference between two types of measurement results is also discussed.
