ION IMAGING DETECTION OF ELECTRON TRANSFER IN RYDBERG ATOM - SODIUM DIMER INTERACTIONS C.Gebauer-Rochholz, O.Kaufmann, and K.Bergmann Fachbereich Physik der Universitaet, 67653 Kaiserslautern, Germany Dissociative charge transfer (DCT) from atomic Rydberg states of sodium to vibrationally excited sodium dimers is investigated in a molecular beam experiment. A newly developed imaging setup, which allows the study of state-specific cross sections for the production of Na- ions by this process, is described. New results are presented, if available.
