论文摘要
我们报告了$ 5D_ {3/2} $状态的动态（AC）标量极化的测量值，该$^{85} $ rb原子在激光波长为1064〜nm处。与最近的物理测量相反。修订版\ textbf {a} 104，063304（2021），实验以低强度制度执行，其中AC偏移小于$ 5D_ {3/2} $ State的超精细结构，如在许多实验中所使用的，具有冷，诱人的，诱人的，诱人的，诱捕的原子。提取的AC极化性为$α_{5D_ {3/2}} = -499 \ PM59 $ 〜A.U。，在上述先前结果的不确定性之内。通过分析D1线的光偏移执行的1064〜nm光强度的校准是不确定性的主要来源。我们的结果对于Rydberg原子和分子的RB $ 5D_ {3/2} $的应用非常有用。
We report a measurement of the dynamic (ac) scalar polarizability of the $5D_{3/2}$ state in $^{85}$Rb atoms at a laser wavelength of 1064~nm. Contrary to a recent measurement in Phys. Rev. \textbf{A} 104, 063304 (2021), the experiments are performed in a low-intensity regime in which the ac shift is less than the $5D_{3/2}$ state's hyperfine structure, as utilized in numerous experiments with cold, trapped atoms. The extracted ac polarizability is $α_{5D_{3/2}} = -499\pm59$~a.u., within the uncertainty of the aforementioned previous result. The calibration of the 1064~nm light intensity, performed by analyzing light shifts of the D1 line, is the main source of uncertainty. Our results are useful for applications of the Rb $5D_{3/2}$ state in metrology, quantum sensing, and fundamental-physics research on Rydberg atoms and molecules.
