Weak Interactions in Atomic Physics

宇称禁戒跃迁的高精度计算 在重的，许多电子原子的振幅进行， 对标准模型进行辐射修正。 修正对目前未知的质量不敏感 这使得我们能够灵敏地探测 物理学 多体微扰理论与耦合团簇 技术，包括三重激发， 在Cs原子中进行精确度为0.1%的计算。 此外，还计算了屏蔽Lamb位移， 将采用高电荷离子以提供 与实验QED辐射信息比较 少价电子原子系统的修正。

High accuracy calculations of parity forbidden transition amplitudes in heavy, many--electron atoms are undertaken to provide a test of radiative corrections to the Standard Model. The corrections are insensitive to the presently unknown mass of the top quark, which allows a sensitive probe of the new physics. Many body perturbation theory and coupled cluster techniques, including triple excitations are required to perform the calculations to an accuracy of .1% in the Cs atom. In addition, a calculation of the screened Lamb shift in highly charged ions will be undertaken in order to provide information to compare with experimental QED radiative corrections in few valence electron atomic systems.
