用磁瓶电子谱仪研究了Xecore-空穴态的四重俄歇衰变。电子和离子的高收集效率使得能够对所有发射的电子和产物进行六重符合测量。虽然在不同的俄歇台阶发射的俄歇电子大大重叠彼此的能量，一步一步的分析俄歇电子之间的能量相关性符合揭示了两个重要的四重俄歇衰变途径。
The sequential quadruple Auger decay of the Xecore-hole state has been investigated by multielectron-ion coincidence spectroscopy using a magnetic bottle electron spectrometer. The high collection efficiency for electrons and ions enables sixfold coincidence measurement of all the emitted electrons and the production. While the Auger electrons emitted in the different Auger steps greatly overlap each other in energy, step-by-step analysis of the energy correlation among Auger electrons in coincidence discloses two important quadruple Auger decay pathways.
