用一种新的电子-电子符合装置研究了C1 s光电离激发CO的K-VV俄歇谱。的能量分辨率是足够高的，以解决核心电离的中间状态和大多数双阳离子的最终状态在二维电子能量图的振动能级。我们演示了如何振动状态对分子俄歇光谱的影响，可以通过实验来访问，而不需要平均所有中间态能量的约束。
The K-VV Auger spectrum of carbon monoxide (CO) excited by C 1s photoionization has been investigated with a novel electron-electron coincidence setup. The energy resolution is sufficiently high to resolve the vibrational energy levels of the core-ionized intermediate state and of most dicationic final states in the two-dimensional electron energy map. We demonstrate how the influence of vibrational states on a molecular Auger spectrum can be accessed experimentally without the constraint of averaging over all intermediate state energies.
