The angle between the molecular axis and the projectile was obtained by using a momentum imagining technique and isolating the events in which the D+2(1sσ) ions are excited to the vibrational continuum and subsequently dissociate. While anisotropic cross sections have been observed in the past for a number of collision processes involving both target electrons, the one electron process investigated here is isotropic within our experimental uncertainties.© American Physical Society (APS).
