测量了激光蒸发的钒原子与苯蒸气反应生成的夹心钒苯团簇Vn-（benzene）n + 1（n = 1-5）的光电离效率（PIE）曲线。一个双棒激光蒸发源用于提高生产的较大的集群。首次在实验上探测了夹心团簇的次低电离能。三明治团簇的PIE曲线清楚地表明团簇具有准带电子结构，这是一维三明治结构的结果。
Photoionization efficiency (PIE) curves were measured for sandwich vanadium-benzene clusters, V n -(benzene) n + 1 (n = 1-5), which were produced by the reaction of laser-vaporized vanadium atoms with benzene vapor. A two-rod laser vaporization source was used for enhancing the production of the larger clusters. The second lowest ionization energies of the sandwich clusters were probed experimentally for the first time. The PIE curves of the sandwich clusters clearly present evidence that the clusters take a quasi-band electronic structure which results from a one-dimensional sandwich structure.
