【 摘 要 】

Angular and energy distributions of electron emitted from dressed ions and neutral atoms in collisions with atoms and molecules were measured for intermediate incident energies. Effects of the initial state of the projectile electron were studied using distorted wave and CTMC calculations. Experiments carried out on collisions with He, Li, H, Ne, and Ar show that the electron loss distributions depend very strongly on the target.
