The calculation of single ionization cross sections for heavy-ion impact on H2 by applying the continuum-distorted-wave-eikonal-initial-state model was discussed. A representation of the bound-state initial wave function was used which takes into account the molecular character of the target. The two-effective-center approximation was used to describe the final continuum state. The analysis of interference effects and the dependence of the oscillation frequency with the projectile velocity and ejection angle were also presented.
