论文摘要
我们在激光冷却的$^{85} $ rb原子的合奏上使用MM-WAVE光谱验证了$ np_ {1/2} $ rydberg状态的超细结构。我们的测量中的系统不确定性是由两个rydberg原子之间的杂散磁场引起的Zeeman分裂和偶极 - 偶极相互作用的，并以获得的统计不确定性考虑了。我们对$ np_ {1/2} $ Hyperfine耦合常数的最终测量为$ a _ {\ text {hfs}} = 1.443（31）$ 〜GHz。该测量对于与涉及$ NP_ {1/2} $原子的偶极 - 偶极相互作用的远程Rydberg分子，Rydberg电磁和量子模拟的研究很有用。
We measure the hyperfine structure of $nP_{1/2}$ Rydberg states using mm-wave spectroscopy on an ensemble of laser-cooled $^{85}$Rb atoms. Systematic uncertainties in our measurement from the Zeeman splittings induced by stray magnetic fields and dipole-dipole interactions between two Rydberg atoms are factored in with the obtained statistical uncertainty. Our final measurement of the $nP_{1/2}$ hyperfine coupling constant is $A_{\text{hfs}}=1.443(31)$~GHz. This measurement is useful for studies of long-range Rydberg molecules, Rydberg electrometry, and quantum simulation with dipole-dipole interactions involving $nP_{1/2}$ atoms.
