Quantum tunnelling reactions play an important role in chemistry when classical pathways
are energetically forbidden, be it in gas-phase reactions, surface diffusion or liquid-phase …

Bimolecular reaction and collision complexes that drive atmospheric chemistry and
contribute to the absorption of solar radiation are fleeting and therefore inherently …

This roadmap article highlights recent advances, challenges and future prospects in studies
of the dynamics of molecules and clusters in the gas phase. It comprises nineteen …

A novel method of spectroscopy in ion traps termed leak-out spectroscopy (LOS) is
presented. Here, mass-selected, cold ions are excited by an infrared laser. In a subsequent …

The reaction between He+ and CH 3 F forming predominantly CH 2+ and CHF+ has been
studied at collision energies E coll between 0 and k B· 10 K in a merged-beam apparatus …

The energy dependence of the rates of the reactions between He+ and ammonia (NY3,
Y={H, D}), forming NY2+, Y and He as well as NY+, Y2 and He, and the corresponding …

The fully state-selected reactions between H2+ molecules in the X+ 2Σg+ (v+= 0, N+= 0)
state and HD molecules in the X 1Σg+ (v= 0, J= 0) state forming H3++ D and H2D++ H have …

The reactions of He+ with OCS and CO2 have been studied at collision energies between∼
kB⋅ 200 mK and∼ kB⋅ 30 K by merging a beam of Rydberg He atoms with rotationally cold …

We report on an experimental and theoretical investigation of the He++ N2 reaction at
collision energies in the range between 0 and kB· 10 K. The reaction is studied within the …

The reactions between ground-state H-2 (+)(X-2 Sigma (+)(g)(v= 0, J= 0)) and D-2 forming
HD2++ H and H2D++ D were investigated in the range of collision energies E-coll between …
