Projectile charge-state dependence of transfer ionization to single capture ratio in collisions of multiply charged ions with He
- J.R. Macdonald Laboratory, Kansas State University, Manhattan, Kansas 66506 (United States)
The ratios of the cross sections for the processes of transfer ionization (TI) and single capture (SC) were measured for 2 MeV/u Cl{sup 7+,9+,13+,14+,15+} and Ti{sup 15+,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}{sub TI}/{sigma}{sub 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. {copyright} {ital 1997} {ital The American Physical Society}
