<!-- @page { size: 21cm 29.7cm; margin: 2cm } P { margin-bottom: 0.21cm } --> We employ the independent-event model to study the transfer-ionization (TI) process in H+, He2+ + He collisions. We consider both the ionization-capture and capture-ionization paths. The single-particle probabilities for all channels are calculated with the continuum distorted wave eikonal initial state model. With the probabilities for TI we calculate doubly differential and total cross sections which are compared with the available experimental data. Our present results are in better agreement with the experiments than present calculations using the independent-electron model and previous calculations using the independent-even model, but with single particle probabilities calculated with the continuum distorted-wave model.
