Dissociative recombination of H+2 has been studied in the CRYRING ion storage ring (Stockholm). A simple position-sensitive detector has been used that consists of a wedged shaped Cu-foil in combination with a surface-barrier detector. Product state information has been obtained. It turns out that at small electron energies H(n>2) states are formed if energetically possible. No H(ls)+Hls) fragments are observed. At higher electron energies (>12 eV) two excited hydrogen atoms are formed. The results at small electron energy show dynamics very similar to that observed in multi-photon excitation studies in molecular hydrogen. The resolving power of our detector was insufficient to monitor the vibrational population in the beam.
