Abstract
We have calculated doubly differential cross sections (DDCS) for electron emission in 3.6 MeV/amu Au53+ collisions with neon and argon atoms in the continuum distorted wave with eikonal initial state approximation. DDCS for a given final charge state of the recoil ion are extracted from the differential ionization probabilities by use of a binomial analysis. Our results are in very good agreement with experimental data for net- and single-electron emission, when the calculations are based on the optimized potential method to describe the target atom. By contrast, artificial structures in the low-energy continuum are found if a Hartree–Fock–Slater model potential is used for argon targets.
