We study the vicinage effects in the interaction of H2+ projectiles with C, Al, Si, Al₂O₃ and SiO₂ targetsconsidering the excitation of inner shells. On one side we extend the use of the semiclassical impactparametermodel for the excitation of atomic shells, considering quantum corrections and the role of targetscreening in the vicinage effects. On the other hand, we adapt our extended wave packet model (EWPM) [3] tothe calculation of stopping ratios and ionization cross sections for correlated ions. Lindhard model is used toevaluate valence electrons contributions.
