N2 - Translational energy spectra of H− ions have been measured for capture dissociation of 6 keV H2+ molecular ions in collision with H2 gas. Voltage separation of the ion spectra has been obtained by the application of a biasing potential to the collision gas cell, allowing the sequence of processes taking place in different regions of the spectrometer to be identified. The energy release distribution of the H− spectra and a correlation with the corresponding component of the H+ spectra indicate that the majority of H− are produced from single electron capture-dissociation of H2+ in a double-collision mechanism, H2+ + H2 → H2* + [H2+] and H2* + H2 → H− + H+ + [H2], in which high Rydberg states of the H2* molecule are involved.
