论文摘要
我们提出了相对论的多体计算原子和分子席夫的相互作用常数，包括使用原子高斯基础集合专门针对Schiff相互作用进行优化的原子高斯基集。我们目前采用高斯核密度功能的最佳结果是$α_ {\ text {sm}} =（0.364 \ pm 0.025）\ times 10^{ - 17} \ frac {e \ frac {e \ text {cm}}} {e \ text {e \ text {fm}^3} $ $α_ {\ text {sm}} =（-2.40 \ pm 0.24）\ times 10^{ - 17} \ frac {e \ text {cm}} {e \ text {fm}^3} $ for atomic $^{199} $ hg，和$ hg，和$ hg，39 7 3600）$ a.u.对于分子$^{205} $ tlf中的thallium核。我们讨论了我们目前的结果与原子$^{129} $ Xe和$^{199} $ HG的早期计算之间的协议和差异。使用$ {\ cal {p，t}} $的最新测量值 - 奇数电偶极矩和当前的相互作用常数可靠的上限在$^{199} $ hg和$^{205} $ tl nuclei的Schiff矩上，以单个源假设的背景确定。
We present relativistic many-body calculations of atomic and molecular Schiff-moment interaction constants including interelectron correlation effects using atomic Gaussian basis sets specifically optimized for the Schiff interaction. Our present best results employing a Gaussian nuclear density function are $α_{\text{SM}} = (0.364 \pm 0.025) \times 10^{-17} \frac{e \text{cm}}{e \text{fm}^3}$ for atomic $^{129}$Xe, $α_{\text{SM}} = (-2.40 \pm 0.24) \times 10^{-17} \frac{e \text{cm}}{e \text{fm}^3}$ for atomic $^{199}$Hg, and $W_{\text{SM}} = (39967\pm 3600)$ a.u. for the thallium nucleus in the molecule $^{205}$TlF. We discuss agreements and discrepancies between our present results and those from earlier calculations on the atoms $^{129}$Xe and $^{199}$Hg. Using the most recent measurements of ${\cal{P,T}}$-odd electric dipole moments and the present interaction constants reliable upper bounds on the Schiff moments of the $^{199}$Hg and $^{205}$Tl nuclei are determined in the context of a single-source assumption.
