Abstract

There are several types of sources for clusters or free radicals presently in existence. However, apart from mass distributions, ionization potentials, and some chemical reactivity data, very little is known so far about these new states of matter. Neither the electronic structure nor the geometric structure of the various clusters are known so far. The reason for this lack of information is the low density of clusters in the beam produced by today's sources. Nevertheless, having an intense VUV-soft x-ray FEL-based source available it will be feasible to study the electronic structure and, to some extent, the geometric structure of mass selected clusters.
