【 摘 要 】

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.
