This work presents coincidence measurements of multiple ionization cross
sections resulting from charge transfer, projectile electron loss and
direct ionization processes for 1.3 up to 3.5 MeV C3+ ions colliding with
He, Ne, Ar, Kr, and Xe. The present data  shows the increasingly importance
of the multiple ionization channels when the projectile changes its charge
state.=20
