论文摘要
我们报告了$ {}^2 S _ \ frac 1 2 + {}^3p_1 $ -asymptote在$ {}}^{87} $ rb和$ rb and $ {}^170} $ yb中的首次观察光照相。在跨越0.1 GHz和11 GHz之间的结合能的搜索中，在3.1 GHz左右检测到一对种间PA共振。这些共振的特征在于提取PA速率，结合能和Zeeman偏移系数。使用这些共振之一，进行了2-Photon-PhotoAssociaton，从而改善了电子基态下两个最小结合状态的结合能的先前测量，并证明了跨结构光相关作为一种强大的光谱工具。我们讨论对在绝对基态下进入RBYB分子的途径的含义。
We report on the first observation of photoassociation near the ${}^2 S _\frac 1 2 + {}^3P_1$-asymptote in a mixture of ${}^{87}$Rb and ${}^{170}$Yb. In a search spanning binding energies between 0.1 GHz and 11 GHz, a single pair of interspecies PA resonances is detected around 3.1 GHz. These resonances are characterized by extracting PA rates, binding energies and Zeeman shift coefficients. Using one of these resonances, 2-photon-photoassociaton is performed, improving on previous measurements of the binding energies of the two least bound states in the electronic ground state and demonstrating intercombination line photoassociation as a powerful spectroscopic tool. We discuss implications for pathways towards RbYb molecules in the absolute ground state.
