论文摘要
超速制度中的化学能够使原子与分子之间的完全量子控制的相互作用，从而导致在化学反应中发现了隐藏的机制，通常在高温下的热平均值触发。最近，基于激光冷却技术，已经将几个硅藻分子冷却至超低状态，但是与这些简单分子相关的化学反应受到了极大的限制。相比之下，自由基在许多重要的化学反应中起着重要作用，但尚未将其冷却至降低。在这里，我们提出了一种新颖的方法，即减速\ ce {ch3}，这是最简单的多原子自由基，并通过行驶波磁性放电剂同时使用锂原子。该方案为共同捕获\ ce {ch3}和锂铺平了道路，因此可以使用同情的冷却来制备超低自由基样品。
Chemistry in the ultracold regime enables fully quantum-controlled interactions between atoms and molecules, leading to the discovery of the hidden mechanisms in chemical reactions which are usually curtained by thermal averaging in the high temperature. Recently a couple of diatomic molecules have been cooled to ultracold regime based on laser cooling techniques, but the chemistry associated with these simple molecules is highly limited. In comparison, free radicals play a major role in many important chemical reactions, but yet to be cooled to submillikelvin temperature. Here we propose a novel method of decelerating \ce{CH3}, the simplest polyatomic free radical, with lithium atoms simultaneously by travelling wave magnetic decelerator. This scheme paves the way towards co-trapping \ce{CH3} and lithium, so that sympathetical cooling can be used to preparing ultracold free radical sample.
