报道了用传统的单通道光电子能谱直接测量双芯空穴振荡态，为研究这类物质提供了一种新的、相对容易的方法。高质量的结果产生准确的能量和双芯空穴状态的寿命。它们的光电子能谱也可以被比作一个奇异的氩离子与一个核心空缺的吸收，提供了新的信息，这两个不寻常的离子状态，以及中性原子的光谱。
Direct measurements ofdouble-core-hole shake-up states are reported using conventional single-channel photoemission, offering a new and relatively easy means to study such species. The high-quality results yield accurate energies and lifetimes of the double-core-hole states. Their photoemission spectrum also can be likened toabsorption of an exotic argon ion with acore vacancy, providing new information about the spectroscopy of both this unusual ionic state as well as the neutral atom.
