Abstract
A model for post-collision interaction is introduced, emphasizing the adiabatic Stark mixing of autoionizing target states in the field of the receding projectile ion. Parity is destroyed as a good quantum number for the Stark-mixed states. As a consequence the angular distribution of the autoionization electrons exhibits deviation from 90° symmetry. Recent experiments on the He and states excited by 10-keV confirm this result.
