我们描述了在一个新的两物种磁光阱中超冷NaCs+分子形成的实验观察。我们用类似于钠阱中观察到的光缔合电离途径来解释我们的观察结果：Na+ Cs+ prognosis ω Na+ prognosis ω Cs→ NaCs++ e−。我们已经直接测量了NaCs+生产率作为激发激光频率和强度的函数，阐明了基态超精细水平的作用。我们已经观察到共振结构的频率依赖的离子速率，我们与分子的字符的过程。
We describe the experimental observation of ultracold NaCs+ molecular formation in a novel two-species magneto-optical trap. We interpret our observations in terms of a photoassociative ionization pathway similar to that observed in a sodium trap: Na+ Cs+ ħ ω Na+ ħ ω Cs→ NaCs++ e−. We have directly measured the NaCs+ production rate as a function of the excitation laser frequency and intensity elucidating the role of ground-state hyperfine levels. We have observed resonance structures in the frequency-dependent ion rate which we associate with the molecular character of the process.
