论文摘要
大规模的$ \ textit {ab intio} $计算电场梯度的计算，构成了对电动四极杆高素质恒定$ b $的电子贡献，以$ 5S^25p6s $ $ $ $^{1,3} \！p^{1,3} \！ Dirac-Hartree-fock方法和基于配置相互作用dirac-fock-sturm理论的第四种方法。对于$ 5S^25p6s $ $^{1} \！从colineAr激光光谱测量值中提取$^{（117-131）} $ sn的锡同位素的核四极矩，$ q $。为了提供$ 5S^25p6s \，^{1} \！p^{\ rm o} _1 $状态的最终$ b/q $值的最终$ b/q $值提供现实的理论不确定性。
Large-scale $\textit{ab initio}$ calculations of the electric field gradient, which constitutes the electronic contribution to the electric quadrupole hyperfine constant $B$, were performed for the $5s^25p6s$ $^{1,3}\!P^{\rm o}_1$ excited states of tin, using three independent computational strategies of the variational multiconfiguration Dirac-Hartree-Fock method and a fourth approach based on the configuration interaction Dirac-Fock-Sturm theory. For the $5s^25p6s$ $^{1}\!P^{\rm o}_1$ state, the final value of $B/Q =703(50)$ MHz/b differs by $0.4\%$ from the one recently used by Yordanov ${\it et~al.}$ [Communications Physics ${\bf 3}$, 107 (2020)] to extract the nuclear quadrupole moments, $Q$, for tin isotopes in the range $^{(117-131)}$Sn from collinear laser spectroscopy measurements. Efforts were made to provide a realistic theoretical uncertainty for the final $B/Q$ value of the $5s^25p6s\,^{1}\!P^{\rm o}_1$ state based on statistical principles and on correlation with the magnetic dipole hyperfine constant $A$.
