Relative cross sections for the 4 MeV H{sup +}+D{sub 2} ({sup 1}{sigma}{sub g}{sup +}){yields}H{sup +}+D{sub 2}{sup +}(1s{sigma})+e{sup -} ionization process were measured as a function of the molecular alignment during the interaction. 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{sub 2}{sup +}(1s{sigma}) 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.
