Quantum interferences in single ionization of He by highly charged dressed-ions impact

Abstract

Ionization of He targets by impact of partially stripped ions is investigated by means of an extension to the continuum distorted wave-eikonal initial state model with a particular representation of the projectile potential. Structures appearing superimposed on the binary encounter peak are interpreted in terms of coherent interference of short- and long-range contributions of the perturbative projectile potential. The case of 600 keV u−1Au11+ ionsimpinging on He is presented and discussed.
