Abstract Cross-section ratios σTI/σSC of transfer ionization (TI) to single capture (SC) of Cq+- and Oq+-He (q=1-3) collisions in the energy range of 15--440keV/u (0.8--4.2vBohr) are experimentally determined. It is shown that σTI/σSC strongly depends on the projectile velocity, and there is a maximum for E(keV/u)/q1/2≈150. Combining the Bohr--Lindhard model and the statistical model, a theoretical estimate is presented, in reasonable agreement with the experimental data when E(keV/u)/q1/2 >35.
