Dissociation and electron capture of CO+ and CF+ ions in collisions with He, Ne and Ar atoms

The cross sections of collisional dissociation and electron capture have been measured for CO+ and CF+ ions on He, Ne and Ar atoms in the energy range from 4 to 16 keV. Most of the values are interpreted in a common framework of classical one electron model. The electronegative properties of C, O and F appear when the projectile ions dissociate simply. (author)
