原子 Tl 的电偶极矩 (EDM) 增强因子引起了人们极大的兴趣，因为它已被用于确定迄今为止电子 EDM 的最准确极限。然而，其值因不同的近似值而异。鉴于许多这些计算都存在很大的不确定性，我们采用相对论耦合团簇理论进行精确计算并获得结果，并结合 Tl EDM [Phys.莱特牧师。 88, 071805 (2002)PRLTAO0031-900710.1103/PhysRevLett.88.071805] 给出了电子 EDM 的新极限：。
The electric dipole moment (EDM) enhancement factor of atomic Tl is of considerable interest as it has been used in determining the most accurate limit on the electron EDM to date. However, its value varies fromtoin different approximations. In view of the large uncertainties associated with many of these calculations, we perform an accurate calculation employing the relativistic coupled-cluster theory and obtain, which in combination with the most accurate measurement of Tl EDM [Phys. Rev. Lett. 88, 071805 (2002)PRLTAO0031-900710.1103/PhysRevLett.88.071805] yields a new limit for the electron EDM:.
