论文摘要
原子能水平的高细胞结构（HFS）是由于原子电子与核多极矩的层次结构的相互作用而产生的，包括磁偶极子，电二极管和更高的等级矩。最近，从中性$ {}^{}^{173} \ Mathrm {yb} $ [pra 87，012512（2013）]和IS四级核能范围更大的核能范围的核心理论中报告了$^{173} \ mathrm {yb} $ nucleus的磁性八极矩的确定。考虑到光谱提取的价值与核理论之间的这种巨大差异，我们在这里建议使用替代系统来解决这种张力，这是相同$^{173} \ MATHRM {YB} $同位素的单一充电离子。利用大约$ \ mathrm {yb}^+$开发的大量工具用于量子信息应用程序，我们建议通过在长期以来一直活着的首个激动状态下测量超精美拆分来提取核八度核和十六进制矩（$ 4f^{13}}（13}}（^2}（^2}）） $^{173} \ mathrm {yb}^+$。我们提出了原子结构计算的结果，以支持拟议的测量。
Hyperfine structure (HFS) of atomic energy levels arises due to interactions of atomic electrons with a hierarchy of nuclear multipole moments, including magnetic dipole, electric quadrupole and higher rank moments. Recently, a determination of the magnetic octupole moment of the $^{173}\mathrm{Yb}$ nucleus was reported from HFS measurements in neutral ${}^{173}\mathrm{Yb}$ [PRA 87, 012512 (2013)], and is four orders of magnitude larger than the nuclear theory prediction. Considering this substantial discrepancy between the spectroscopically extracted value and nuclear theory, here we propose to use an alternative system to resolve this tension, a singly charged ion of the same $^{173}\mathrm{Yb}$ isotope. Utilizing the substantial suite of tools developed around $\mathrm{Yb}^+$ for quantum information applications, we propose to extract nuclear octupole and hexadecapole moments from measuring hyperfine splittings in the extremely long lived first excited state ($4f^{13}(^2\!F^{o})6s^2$, $J=7/2$) of $^{173}\mathrm{Yb}^+$. We present results of atomic structure calculations in support of the proposed measurements.
