Ion Pair Formation of Sulfur Dioxide in the Energy Range 14–20 eV

Keywords: Rydberg states, pair formation, negative ion yield

The photoinduced ion yield curve of O^- from gaseous sulfur dioxide shows remarkable structures in the energy range between 14 and 20 eV. Their analysis reveals that they image different vibrationless and vibrationally excited Rydberg states converging to the ionic states C, D, E, F. In addition S^-, SO^- and SO₂^- have been observed. Besides ion pair formation small contributions from dissociative electron attachment are recognized.
