摘要：

The photon emission following the excitation to an intermediate decaying state which interacts with other electronic states is discussed in some detail. Particular attention is paid to resonant x-ray emission in symmetric polyatomic systems. The decaying core-excited state always possesses partner states to which it couples through the nontotally symmetric nuclear motion. The resulting dynamical symmetry breaking induces localization of the core holes and may have considerable impact on the intensity and selection rules. The effect of vibronic coupling, lifetime of the decaying state and of temperature are analyzed and interpreted. © 1995 American Institute of Physics.
