Unitarized-distorted-wave-approximation calculations based on a complete set of channels are performed to obtain ionization, excitation, and charge-transfer cross sections for impacts of H/sup +/, Li/sup 3 +/, B/sup 5 +/, C/sup 6 +/, Si/sup 14 +/ ions on atomic hydrogen. The ionization channels are respresented by Coulomb wave functions centered on the projectiles to account for ''charge transfer to the continuum.'' The ionization cross sections depend less than in a quadratic relationship on projectile charge. The inclusion of ionization and excitation channels makes charge-transfer cross sections considerably smaller for higher values of the projectile charge at impact energies above 10 keV/amu. A new scaling rule to charge-transfer cross sections is discussed in comparison with experiments and other theories for the energy range 0.01--5000 keV/amu.
