Resumen:
In this article we report ionization cross sections of neutral He, Ne, Ar, Kr, and Xe by impact of He+ ions with
energies ranging from 25 to 1000 keV/amu. A general theory to deal with dressed projectiles is developed in the
context of the Continuum-Distorted-Wave Eikonal-Initial-State approximation. The strategy is based on the use
of an effective charge defined in terms of the momentum transfer extracted from the first Born approximation
and extensively used in the local plasma approximation to deal with ions in solids. The difference between the
actual potential of the projectile and the Coulombic effective one used in the distorted wave functions is treated
in first perturbative order. Our results show that the proposed approach gives a very good account of available
experiments.
