Single photon simultaneous core ionization/core excitation (K⁻²V) of the Benzene molecule has been observed experimentally, using synchrotron radiation, by electron coincidence spectroscopy with a magnetic bottle time-of-flight electron spectrometer and reveals a rich spectrum. DFT and Post–Hartree–Fock calculations provide detailed assignments of K⁻²V states. The specific Auger decay of these states has also been determined experimentally with a new technique to improve the energy resolution.

C ₆ H _6中单光子同时K-壳电离/激发：实验和理论

通过同步波辐射，通过具有电磁瓶飞行时间电子光谱仪的电子符合光谱，通过实验观察到了苯分子的单光子同时核心电离/核心激发（K ^-2 V）。DFT和Hartree-Fock后计算提供了K ^-2 V状态的详细分配。这些状态的特定俄歇衰变也已通过实验确定，可以提高能量分辨率。
