The dissociative recombination of vibrationally cold CD[sup +] with electrons 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 structures are observed with prominent peaks at 0.8 eV, 8.6 eV, and 11.7 eV. While the second and third resonance are readily attributed to direct recombination processes through Rydberg levels with dissociating molecular 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 an indirect recombination process.
