摘要：

We have measured strongly negative values of the 3s-participator lines at the magnesium 2p4s and 2p1/23d excitations. Observed values of the spectator lines following 2p4s excitation are not reproduced by the strict spectator model. Our multiconfiguration Dirac-Fock calculations show that the resonant Auger spectra are influenced by unusually pronounced configuration interaction in the excited state. This influence is strongly enhanced by a change of sign in the Auger amplitude of the leading term near the transition energy, a dynamic effect similar to a Cooper minimum in photoionization. © 1994 The American Physical Society.
