摘要：

Photoelectrons originating from sulfur dioxide cluster anions were studied using a tandem mass spectrometer combined with an electron detector and intracavity argon-ion and dye lasers. The absolute photodetachment cross section of the dimer anion increases to (8 +/- 1) x 10(-19) cm2 at 2.71 eV photon energy. Electrons detected from the interaction of photons with sulfur dioxide clusters were found to be produced in sequential two-step processes only, revealing a lower bound of the cluster's detachment threshold energy of 2.7 eV.
