Anion and cation emission via binary-encounters in OH+ + Ar collisions: The role of dissociative excitation and statistical aspects

Emission of H− and H+ ions via nucleus-nucleus collisions were observed in OH+ + Ar collisions in wide angular range. They show similar angular distributions, which indicate a statistical distribution of the final charge states. Non-vanishing emission at small angles show that dissociative excitation of the projectile has a crucial role in the process.
