摘要：

Interference effects for electron emission in collisions between molecules and fast highly charged ions are studied using a nonperturbative semiclassical approach. Angle- and energy-differential results are presented and analyzed as a function of the projectile charge and velocity, as well as the geometric characteristics of the molecular target. They agree qualitatively with the available experimental data and validate the observed primary interference patterns. Contrary to previous theoretical predictions a strong backward-forward asymmetry of the interference structures is found and discussed in detail.
