Abstract
Dissociative recombination (DR) is an exothermic process leading to neutralisation and chemical fragmentation in many plasma environments, down to the lowest temperatures. We present results of complex investigations on DR of HF+ and CF+ performed at the TSR storage ring. Beyond the rate coefficient down to meV collision energies also dissociation pathways and geometries have been investigated using full 3D fragment imaging technique. Fragment imaging also provides HF+ rotational structure and fine-structure as well as the HF+ dissociation energy with sub-meV precision.
