我们通过结合低温源和行波Stark减速器证明了重极性分子在低场寻找状态下的减速。低温源提供了低速度和低温度的高强度光束，行波减速器提供了大的减速力和高相空间接受度。我们用YbF分子证明了这些技术，并发现实验数据与数值模拟非常吻合。这些方法将斯塔克减速的范围扩展到非常广泛的分子。
We demonstrate the deceleration of heavy polar molecules in low-field-seeking states by combining a cryogenic source and a traveling-wave Stark decelerator. The cryogenic source provides a high-intensity beam with low speed and temperature, and the traveling-wave decelerator provides large deceleration forces and high phase-space acceptance. We prove these techniques using YbF molecules and find the experimental data to be in excellent agreement with numerical simulations. These methods extend the scope of Stark deceleration to a very wide range of molecules.
