We present a combined experimental and theoretical study of cold reactive collisions
between laser-cooled Ca+ ions and Rb atoms in an ion-atom hybrid trap. We observe rich …

Since Arrhenius first proposed an equation to account for the behavior of thermally activated
reactions in 1889, significant progress has been made in our understanding of chemical …

Many molecules exhibit multiple rotational isomers (conformers) that interconvert thermally
and are difficult to isolate. Consequently, a precise characterization of their role in chemical …

Multipole radiofrequency ion traps are a highly versatile tool to study molecular ions and
their interactions in a well-controllable environment. In particular the cryogenic 22-pole ion …
