The Ion Trap Group has in collaboration with the Max-Planck-Institut für Kernphysik (MPIK), Heidelberg, Germany, carried out the first helium buffer gas cooling experiments on molecular ions sympathetically cooled into a Coulomb crystal. The applied method constitutes a novel route to form cold and spatially localized molecular ions. The results open up for refined studies of molecules and molecular processes in a size-range spanning from the smallest diatomic molecular ions to complex molecules of biological relevance. In terms of science, the results are expected to have impact on such diverse fields as fundamental physics investigations, high-resolution spectroscopy of complex molecules, cold chemistry, astrochemistry, as well as biochemistry.
