Electron attachment reactions in mixed SF6/N2 clusters

Low energy (0–6 eV) electron attachment to clusters composed of SF6 and N2 yields (SF6)n− and anionic complexes containing SF6 and N2. The energy profile for the formation of these anions indicates strong contributions due to inelastic electron scattering via the N2−(2Π) resonance followed by intracluster electron transfer. This scattering feature peaks near 2 eV at low stagnation pressure and is shifted to 1.5 eV at 7 bar. The significant shift of the N2− resonance towards lower energy with respect to the gas phase (2.3 eV) is due to the solvation of N2− and the electron transfer behavior between N2− and SF6.
