Relative double differential cross sections for electron emission from collisions of 0.6 MeV amu^-1I⁷⁺and I²³⁺ projectiles with Ar and Au¹¹⁺projectiles with He were measured for electron energies from 100 eV to 2000 eV and for angles from 0° to 50°. Experimentally observed sudden shifts of the position of the binary encounter peak were interpreted as resulting from quantum interference in the scattering of target electrons from the partially stripped projectile ion. To this end calculations for the elastic scattering of free electrons initially at rest in the laboratory reference frame from the screened …
