Аннотация:A strong alternation of Auger electron angular distributions is observed for the second-step Auger emission of Ar following 2p(3/2) --> 4s and 2p(1/2) --> 4s excitation. This effect, which gives rise not only to anisotropy suppression but also to the strong enhancement, is shown to originate from a coherent population of the Anger initial state due to the short decay time of the second-step Anger transition, the so-called lifetime interference effect.
