This project aims at using ICD as a highly selective tool to create two charges on two neighboring atom in a cluster and to study the cluster dynamics driven by these charges. We will use a powerful multiparticle coincidence technique to measure mass, energy and direction of the charged cluster fragments together with energy and direction of the ICD electron and the photo/auger electron. The excitation/ionization which initializes ICD will be done in two ways: by direct photoionization/exciation and via resonant Auger decay where an inner shell electron is excited to a bound state. This resonant Auger (RA)-ICD cascade process has never been studied before; it is the topic of the theory proposal by Gokhberg/Cederbaum. We will use pure He and Ne clusters as well as mixed rare gas clusters at varying cluster sizes. This will provide a picture of the cluster dynamics and the modifications of the ICD process by the environment, which is unprecedented in completeness and detail.

本项目旨在利用ICD作为一种高选择性的工具，在一个团簇中的两个相邻原子上产生两个电荷，并研究由这些电荷驱动的团簇动力学。我们将使用一种强大的多粒子符合技术来测量带电团簇碎片的质量、能量和方向，以及ICD电子和光俄歇电子的能量和方向。激发/电离将以两种方式进行：直接光致电离/激发和共振俄歇衰变，其中内层电子被激发到束缚态。这种共振俄歇(RA)-ICD级联过程以前从未被研究过，这是Gokhberg/Cederbaum提出的理论建议的主题。我们将使用不同大小的纯He和Ne星系团以及混合稀有气体星系团。这将提供一幅关于集群动态和环境对ICD进程的修改的图景，其完整性和细节都是前所未有的。
