摘要：

The ratios of the cross sections for the processes of transfer ionization (TI) and single capture (SC) were measured for 2 MeV/u Cl-7+,Cl-9+,Cl-13+,Cl-14+,Cl-15+ and Ti-15+,Ti-18+ projectile ions on He targets. The ratio was determined using a cold He gas target and measuring the coincidences between the projectile and the charge states of the emerging recoil ions. The measured sigma(TI)/sigma(SC) ratio shows a strong dependence with the projectile charge state that is well described by calculations based on the independent electron model. A model to take into account the effect of the electron screening of partially dressed projectiles in the target ionization is also presented.
