Dissociation of D₂ molecules in collisions with multiply charged ions

Abstract

Dissociative electron capture has been studied in low — energetic collisions of multiply charged ions with simple diatomic molecules (H₂, D₂;E ∼ (1 *q) keV). The different possible capture reactions are separated with the aid of time-of-flight spectra, which are obtained by the coincident measurement of projectile and recoil ions. In particular, we discuss the relative importance of dissociative single electron capture, its dependence on the projectile scattering angle as well as the type of the involved molecular transition.
