Abstract
The ratios of the cross sections for the formation of H+ and H2+ from H2 by the impact of fast fully stripped ions (C6+, O8+, S16+) have been measured at various incident projectile energies in order to understand the projectile charge and energy dependence on two-electron processes. The measured values have been corrected for the small contribution from dissociative ionization through single electron process. A comparison of the existing low charge projectile data with the present measurements tends to show a universal scaling behaviour for projectile charge and velocity.
