论文摘要
我们提出了对Rubidium离子核心极化性的精确测量。该结果对于解释实验，例如违反奇偶校验或原子钟的黑体辐射变化，因为离子核心电子对rubidium的总电极化性有显着贡献。我们报告了偶极极化性$α_d$ = $ 9.116 \ pm 0.009 $ $ $ a_0^3 $和quadrupole极化性$α_q$ = $ 38.4 \ pm 0.6 $ $ a_ {0}^{0}^{5} $衍生自微层和填充型范围的速度测量范围。通过使用相对较低的主量子数（$ 17 \ leq n \ leq 19 $）和高角度动量（$ 4 \ leq \ ell \ leq 6 $），与先前的实验相比，系统效应降低了。我们开发了一种经验方法来解释对极化模型的非绝热校正。校正对$α_d$的效果小于1 \％的效果，但其绝热价值中的更正几乎是$α_Q$的两倍，使其与理论值更加一致。
We present a precise measurement of the rubidium ionic core polarizability. The results can be useful for interpreting experiments such as parity violation or black-body radiation shifts in atomic clocks since the ionic core electrons contribute significantly to the total electrical polarizability of rubidium. We report a dipole polarizability $α_d$ = $9.116 \pm 0.009$ $a_0^3$ and quadrupole polarizability $α_q$ = $38.4 \pm 0.6$ $a_{0}^{5}$ derived from microwave and radio-frequency spectroscopy measurements of Rydberg states with large angular momentum. By using a relatively low principal quantum number ($17 \leq n \leq 19$) and high angular momentum ($4 \leq \ell \leq 6$), systematic effects are reduced compared to previous experiments. We develop an empirical approach to account for non-adiabatic corrections to the polarizability model. The corrections have less than a 1\% effect on $α_d$ but almost double $α_q$ from its adiabatic value, bringing it into much better agreement with theoretical values.
