In this project the combined results of tunneling spectroscopy and of photoelectron spectroscopy performed on size selected large clusters in tunneling contact with a surface as well as of photoelectron spectroscopy on the same clusters in the gas phase will be used to clarify the electronic structure of the cluster/surface system and the nature of charge transfer processes between the cluster and the surface. Furthermore this direct comparison of the three different techniques is expected to improve the understanding of the results of tunneling spectroscopy on metal particles.

在这个项目中，隧道光谱和光电子能谱的综合结果进行的大小选择的大集群隧道与表面接触，以及在气相中相同的集群的光电子能谱将被用来澄清的电子结构的集群/表面系统和集群和表面之间的电荷转移过程的性质。此外，这三种不同技术的直接比较有望提高对金属颗粒隧道光谱结果的理解。
