高分辨率共振俄歇光谱已在 ELETTRA (Sincrotrone Trieste) 的 VUV 光束线上测量，同时调整氩气 2 p 3/2− 1 3 d 共振的光子能量。观察到衰减到观察者 3 p− 2 3 d 和抖动 3 p− 2 4 d 通道的分支比的巨大变化。这种效应以前在共振内壳激发中没有见过，归因于直接光电离过程和共振俄歇衰变之间的干扰，导致相同的最终状态。
High resolution resonant Auger spectra have been measured at the VUV beam line at ELETTRA, Sincrotrone Trieste, while tuning the photon energy across the 2 p 3/2− 1 3 d resonance of argon. A large variation of the branching ratio for decay into the spectator 3 p− 2 3 d and shakeup 3 p− 2 4 d channels is observed. The effect has not been seen previously in resonant inner-shell excitation and is attributed to the interference between the direct photoionization process and resonant Auger decay leading to the same final state.
