基态分子的AC电陷阱

An AC electric trap for ground-state molecules

Jacqueline van Veldhoven, Hendrick L. Bethlem, Gerard Meijer

摘要:

我们在这里报告的实现电动势阱,能够捕获中性原子和分子在低场和高场寻求状态。通过在阱中心具有鞍点的两个电场配置之间切换来实现三维限制,即,通过在每个方向上交替聚焦力和散焦力。实验证明了15ND3分子的交流捕获,并研究了陷阱的稳定性作为开关频率的函数。15ND3分子的1 mK样品在高场寻找组件的|J,K>=| 1,1>能级,对位氨的基态,被捕获在约1立方毫米的体积中。

英文摘要:

We here report on the realization of an electrodynamic trap, capable of trapping neutral atoms and molecules in both low-field and high-field seeking states. Confinement in three dimensions is achieved by switching between two electric field configurations that have a saddle-point at the center of the trap, i.e., by alternating a focusing and a defocusing force in each direction. AC trapping of 15ND3 molecules is experimentally demonstrated, and the stability of the trap is studied as a function of the switching frequency. A 1 mK sample of 15ND3 molecules in the high-field seeking component of the |J,K>=|1,1> level, the ground-state of para-ammonia, is trapped in a volume of about 1 mm^3.
