Zusammenfassung: 
The interaction of carbon dioxide positive ions and neutral molecules with clean and potassium covered surfaces is studied by grazing incidence scattering experiments using a time-of-flight (TOP) method. When scattered off Pd surfaces, CO2+/0 projectiles with primary energies of 250-1500 eV are subject to charge exchange processes, which partly lead to dissociation. Violent collisions are less destructive in this energy range (E-perpendicular to approximate to 2-12 eV). Potassium is a well known promoter in surface chemistry and causes an increase of dissociation.
