我们提出了一个实验来测量电偶极矩（EDM）的电子使用超冷YbF分子。这些分子由低温缓冲气体源产生为热束，并在光学糖蜜中静止，该光学糖蜜将它们冷却到多普勒极限或更低。然后，分子云被向上抛出，形成一个喷泉，在喷泉中测量电子的EDM。一个非零的结果将是新的基本粒子相互作用的明确证据，超越了标准模型。
We propose an experiment to measure the electric dipole moment (EDM) of the electron using ultracold YbF molecules. The molecules are produced as a thermal beam by a cryogenic buffer gas source, and brought to rest in an optical molasses that cools them to the Doppler limit or below. The molecular cloud is then thrown upward to form a fountain in which the EDM of the electron is measured. A non-zero result would be unambiguous proof of new elementary particle interactions, beyond the standard model.
