摘要：

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 90â°symmetry. Recent experiments on the He 2s2pP1 and 2p2 D1 states excited by 10-keV Li+ confirm this result. © 1979 The American Physical Society.
