Dissociative and non-dissociative charge-changing processes in 1.0-2.0 MeV/u O5+ + O2 collisions

Abstract

In the present work molecular ionization and dissociation correlated with projectile single electron capture and loss is investigated as a function of energy for O5+ + O2 collisions. Coincidence recoil-ion spectra as well as total projectile charge-changing yields were measured for projectile energies of 1.0, 1.5, and 2.0 MeV/u. Charge states for dissociative and non-dissociative recoiling products of the target molecular oxygen were identified. Ratios of charged molecular fragment yields to single non-dissociative ionization yields as a function of projectile energy were determined as well as total cross sections for projectile single electron capture and loss.
