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 CH3,the simplest polyatomic free radical,with lithium atoms simultaneously by travelling wave magnetic decelerator.This scheme paves the way towards co-trapping CH3 and lithium,so that sympathetical cooling can be used to preparing ultracold free radical sample.
