We study interactions between a strongly-coupled non-neutral crystallised plasma and slow neutral atoms or molecules in order to understand quantum mechanical effects governing ion-neutral reactions.We employ laser cooling to obtain ion ensembles with sub-Kelvin temperatures in a linear Paul trap. Neutral molecules are manipulated by decelerators operating on the principles of Zeeman, Stark, or collisional cooling effects. In this manner, we reduce the number of quantum states taking part in the scattering event to only a few. In order to reduce this number further, we are constructing a Paul trap with a cryogenicallycooled thermal radiation shield.
