We employ the independent-event model to study the transfer-ionization(TI) process in H+, He2+ + He collisions. Weconsider both the ionization-capture and capture-ionization paths. Thesingle-particle probabilities for all channels are calculated with thecontinuum distorted wave eikonal initial state model. With theprobabilities for TI we calculate doubly differential and total crosssections which are compared with the available experimental data. Ourpresent results are in better agreement with the experiments thanpresent calculations using the independent-electron model and previouscalculations using the independent-event model, but with single-particleprobabilities calculated with the continuum distorted-wave model.
