The interest of the present work is focused on theoretical calculations of single electron ionization, single electron capture and transfer-ionization reactions of He targets interacting with bare ion beams. In order to investigate all these processes, the corresponding transition probabilities are determined in the framework of the prior-version of the three-body Continuum Distorted Wave-Eikonal Initial State model (3B-CDW-EIS). A theoretical description using a trinomial probability analysis based on 3B-CDW-EIS is also presented to analyze its limitations for the studied reactions. The cases of He2+ and Li3+ projectiles are considered at intermediate and high collision energies. A unitarization procedure is employed to avoid transition probabilities larger than one at intermediate velocities.
