Abstract
We report on the measurements of double differential cross sections, at zero degree, for the production of secondary electrons from the collision of 0, 6 MeV amu-1 Cu5+, I7+, Au11+, U13+, Cu19+, t23+ and Au29+ projectiles with H2 and He. The shapes and positions of the observed binary encounter electron peaks are compared with continuum distorted wave-eikonal initial state (CDW-EIS), impulse approximation and classical trajectory Monte Carlo calculations, as well as with predictions from an adiabatic resonant tunnelling model recently proposed by Fainstein and co-workers. The experimentally observed binary peak positions were found to be essentially determined by the projectile's ionic charge q and to be independent of the projectile's nuclear charge Zp. Although the experimental conditions correspond to the strong perturbation regime, i.e. 1.0 ≤ q/Vp ≤ 5.9 (Vp being the projectile velocity), the CDW-EIS approach accounts well for the position and shape of the binary peak. © 1993 IOP Publishing Ltd.
