ELECTRON-ATTACHMENT REACTIONS IN MIXED SF6/N-2 CLUSTERS

Low energy (0-6 eV) electron attachment to clusters composed of SF6 and N-2 yields (SF6)(n)(-) and anionic complexes containing SF6 and N-2. The energy profile for the formation of these anions indicates strong contributions due to inelastic electron scattering via the N-2(-)((2) Pi) 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 N-2(-) resonance towards lower energy with respect to the gas phase (2.3 eV) is due to the solvation of N-2(-) and the electron transfer behavior between N-2(-) and SF6.
