Abstract
Single and multiple transitions in p(+/-) + Ne collisions are discussed wit hin an effective single-particle picture relying on an accurate description of the target ground state in terms of the optimized potential method. We show that in the case of proton scattering total cross sections for capture and ionization can be extracted over a broad range of impact energies from the single-particle solutions obtained with the basis generator method. In particular, we analyze the role of dynamical screening effects in multiple ionization and propose a simple model for their inclusion in the case of a ntiproton scattering.
