论文摘要
我们通过组合两个光学镊子,每个光学镊子都包含一个分子,来测量超低CAF分子之间的非弹性碰撞。我们观察到在绝对基态$ | x,v = 0,n = 0,f = 0 \ rangle $的$^2σ$ Caf分子之间的碰撞,以及在激发的超细态和旋转状态下。在绝对基础状态下,我们发现$ 7(4)\ times 10^{ - 11} \ text {cm}^{3}/\ text {s} $的两体损耗率为$ 7(4)\ times 10^{-11} \ text {cm}^{cm}^{3}^{s} $,但接近预测的通用损失率。
We measure inelastic collisions between ultracold CaF molecules by combining two optical tweezers, each containing a single molecule. We observe collisions between $^2Σ$ CaF molecules in the absolute ground state $|X,v=0, N=0,F=0\rangle$, and in excited hyperfine and rotational states. In the absolute ground state, we find a two-body loss rate of $7(4) \times 10^{-11} \text{cm}^{3}/\text{s}$, which is below, but close to the predicted universal loss rate.
