应用于高频共振俄歇谱的波包动力学揭示了选择性激发引入的新颖干涉效应。通过使激发能量脱离共振，这些效应被显着增强。除了通过失谐来猝灭所谓的“原子线”之外，在向更高激发能量的小失谐的情况下，意想不到的突出结构在光谱中占主导地位。通过跟踪过程的实时时间尺度上的物理相关量来识别潜在的干扰机制。 [S0031-9007(97)05272-1]
Wave packet dynamics applied to the resonant Auger spectrum of HF bring to light novel interference effects introduced by selective excitation. By detuning the excitation energy off the resonance these effects are shown to be strongly enhanced. Besides the quenching of the so-called “atomic lines” by detuning, an unexpected prominent structure dominates the spectrum in the case of small detuning towards higher excitation energies. The underlying interference mechanisms are identified by tracing the physically relevant quantities on the real time scale of the process. [S0031-9007(97)05272-1]
