Zusammenfassung / Abstract

This thesis studies interactions of Rydberg atoms with neutral atoms and with single ions. While for the studies of Rydberg atom-neutral interaction the case of one, few, or even many atoms interacting with a single Rydberg electron is investigated, for the ion-Rydberg atom system mostly binary interaction is studied. Beyond that, the level structure of negative ions is explored in the context of ultralong-range Rydberg molecules. The experiments are carried out in a gas made of rubidium-87 atoms at ultracold temperatures, where the motion of atoms is usually frozen out on the time and length scale of such experiments.
