摘要:

精确确定YbF中的有效电场(Eeff)是很重要的,因为它可以与未来的实验结果相结合,给出一个改进的新的限制电子的电偶极矩。它超过了以前报道的计算中的近似值。我们得到一个值为23.1 GV/cm的Eeff在YbF的估计误差小于10%。基组和核心激发在我们的工作中的关键作用进行了讨论。

英文摘要:

An accurate determination of the effective electric field (Eeff) in YbF is important, as it can be combined with the results of future experiments to give an improved new limit for the electric dipole moment of the electron. We report a relativistic coupled-cluster calculation of this quantity in which all the core electrons were excited. It surpasses the approximations made in the previous reported calculations. We obtain a value of 23.1 GV/cm for Eeff in YbF with an estimated error of less than 10%. The crucial roles of the basis sets and the core excitations in our work are discussed.
