Abstract
A soft-core Coulomb potential model in one dimension for the longitudinal electron motion in ion-atom collisions is described. For the proton-hydrogen system the model contains realistic resonant charge transfer in the adiabatic regime. We solve the model numerically by a spatial discretization technique and test different prescriptions for the extraction of differential ionization information. The prescriptions are based on a subtraction of atomic bound-state contributions from the final wavefunction followed by either (i) atomic continuum eigenstate projections, (ii) a method based on the fluid-dynamical formulation of quantum mechanics or (iii) a semiclassical Husimi phase-space analysis. It is found that the location of the maximum in the electron momentum distribution scales with the projectile charge in the opposite direction from the classical saddle-point prediction.
