We have demonstrated that a supersonic beam of methyl radicals (CH$_3$) in the ground rotational state has been slowed down to standstill with a magnetic molecular decelerator, and successfully captured spatially in an anti-Helmholtz magnetic trap for longer than 1 sec. The trapped CH$_3$ radicals have a mean translational temperature of about 200 mK with an estimated density of $>$ 5.0 $\times$ $10^7$ cm$^{−3}$.
The methyl radical is an ideal system for the study of cold molecules not only because of its high reactivities at low temperatures, but also because further cooling below 1 mK is plausible via sympathetic cooling with ultracold atoms. We will discuss properties of cold collisions between the trapped radicals and foreign gases.
