Abstract: Here we present a study on dissociative electron attachment (DEA) to bromotrifluoromethane, CF 3 Br, in the energy range from 0 to 10 eV. The dominating process observed is the formation of Br − close to 0 eV incident electron energy. The fragment ion Br − is also observed through a broad contribution from about 3 to 5 eV. In this energy range, F − , FBr − and CF 2 Br − are also observed, and in the Br − and F − ion yield, a weak contribution is observed close to 8.1 eV. For the DEA processes we calculate the thermochemical thresholds using conventional DFT methods, and the results are discussed in context to these, earlier work and the assignment of the underlying resonances.
