NEW RESONANCES IN THE DISSOCIATIVE RECOMBINATION OF VIBRATIONALLY COLD CD+

The dissociative recombination of vibrationally cold CD+ with electron s in the energy range of 0.01 eV to 60 eV has been measured using the Test Storage Ring in a merged beam arrangement. New resonance structur es are observed with prominent peaks at 0.8 eV, 8.6 eV, and 11.7 eV. W hile the second and third resonance are readily attributed to direct r ecombination processes through Rydberg levels with dissociating molecu lar ion cores, the origin of the first resonance structure is not well understood, however, its small width of 0.45 eV is an indication of a n indirect recombination process.
