The project is aimed at producing an ensemble of ultracold methyl radicals (CH3) which can be used to study the process of nuclear spin conversion, and to produce a Bose-Einstein condensate of polyatomic molecules. To investigate the possibilities of sympathetic cooling using metastable helium atoms (He*), CH3-He* collisions will be studied using spin-polarized samples and spin-statistical mixtures of He*, respectively. To experimentally realize the sympathetic cooling of CH3 by He*, the PhD student will build a Zeeman slower for He*. There is also the possibility to get involved into scattering calculations that will help to understand the cooling mechanism. (K. Dulitz, T. Momose, R. Krems)
