Abstract

We report a combined experimental and theoretical study of an intermediate velocity collision system. Our aim is to investigate the possibility of emitting electrons which are accelerated by the Fermi-shuttle mechanism due to double and triple scattering effects. Electron emission in the 20-2000 eV energy range and in the full angular range of 0°-180° were measured by the impact of 150 keV/u C+ ions on Ne atoms. Classical trajectory Monte-Carlo (CTMC) calculations, show structures belonging to both the projectile-target (P-T) and the target-projectile (T-P) types of double scattering, and signatures for the triple P-T-P scattering. However, T-P and P-T-P shoulders together, calculated by CTMC at forward angles, form a structureless monotonic spectrum. This finding is in agreement with experiment.
