Dissociative and non-dissociative electron capture by keV diatomic molecular ions from noble gases

Abstract

Dissociative and non-dissociative electron capture from atoms by slow molecular ions were investigated by measuring in coincidence the momenta of the recoil ion and the projectile or its fragment pair. From these momenta we evaluate the reaction Q-value as well as the scattering angles. For the dissociative capture we also determine the alignment dependence of the process.
