Research Abstract	We succeeded in producing vibrationally cold OH^+ ion beams using an electrostatic ion trap. The angular dependence of the dissociation of the cold OH^+ ions in dissociative electron capture collisions was investigated. The angular distribution was isotropic, and three-body effects were not observed. Here, the three-body effect means the three-body collision between the individual fragments and the target atom. Vibrationally cold HD^+ ion beams are needed because dissociative electron capture by the HD^+ ions could be influenced by the three-body effect more significantly.
