Abstract: 
The process of electron-loss to the continuum (ELC) has been studied for the collision systems U28+ + H-2 at a collision energy of 50 MeV/u, U28+ + N-2 at 30 MeV/u, and U28+ + Xe at 50 MeV/u. The energy distributions of cusp electrons emitted at an angle of 0 degrees with respect to the projectile beam were measured using a magnetic forward-angle electron spectrometer. For these collision systems far from equilibrium charge state, a significantly asymmetric cusp shape is observed. The experimental results are compared to calculations based on first-order perturbation theory, which predict an almost symmetric cusp shape. Some possible reasons for this discrepancy are discussed.
