凝聚相纯C60的价态的同步辐射和X-射线光电子能谱研究表明，由于涉及簇和自由电子类最终状态的矩阵元素效应，17个不同的分子特征在最高占据分子状态以下延伸约23 eV，强度变化。 赝势计算确立了这些特征的起源，并与实验进行了很好的比较。 尖锐的C1 s主线表明一个单一的物种，和9个卫星结构是由于震动和等离子体特征。 1.9-eV的特征反映了到激发态的最低未占据分子能级的跃迁。
Synchrotron-radiation and x-ray photoemission studies of the valence states of condensed phase-pure C60 showed seventeen distinct molecular features extending approximately 23 eV below the highest occupied molecular states with intensity variations due to matrix-element effects involving both cluster and free-electron-like final states. Pseudopotential calculations established the origin of these features, and comparison with experiment was excellent. The sharp C 1s main line indicated a single species, and the nine satellite structures were due to shakeup and plasmon features. The 1.9-eV feature reflected transitions to the lowest unoccupied molecular level of the excited state.
