We have observed formation of Rydberg series superimposed on the Ar ( L 3 M 2,3 M 2,3 ) Auger electron spectral profile with photoexcitation just above the 2p −1 3/2 photoionization threshold. This is due to the recapture of photoelectrons induced by post-collision interaction between the Auger electron and photoelectron: Ar + 2p −1 3/2 + e − → Ar + 3p −2 ml + e − . The intensity distribution of the angular momentum state resolved Rydberg peaks revealed prominent conjugate peaks due to angular momentum exchange between photoelectrons and Auger electrons in the process. In addition, we measured the 2p −1 3/2 nl → 3p −2 ml + e − resonant Auger spectra with high resolution below the 2p −1 3/2 threshold. Our results showed that conjugate shake-up/down 2p −1...

接近阈值Ar 2p光电离后，高分辨率俄歇电子光谱中的共轭电子捕获峰

我们已经观察到在光激发刚高于2p -1 3/2光电离阈值的情况下，在Ar（L 3 M 2,3 M 2,3）Auger电子光谱轮廓上叠加了Rydberg级数的形成。这是由于俄歇电子与光电子之间的碰撞后相互作用引起的光电子的重新捕获：Ar + 2p -1 3/2 + e-→Ar + 3p -2 ml + e-。由于在此过程中光电子与俄歇电子之间的角动量交换，角动量态解析的Rydberg峰的强度分布显示出突出的共轭峰。此外，我们以低于2p -1 3/2阈值的高分辨率测量了2p -1 3/2 nl→3p -2 ml + e-共振俄歇谱。我们的结果表明，共轭振动向上/向下2p -1 ...
