Abstract

Electron spectra in the 20-550 eV energy range and in the full angular range of 0-180° were measured by the impact of 150 keV/u C+ ions on He, Ne and Ar atoms. Double differential cross sections for electron emission have been determined. We observed an unexpected, broad structure around 300 eV electron energy at backward emission angles relative to the beam direction. Our calculations support the hypothesis that the new structure is due to double scattering of the target electrons on the screened fields of the projectile and the target. The calculations also show that both electron-emitting partners are multiply ionized in the collision.
