Soft X-ray spectroscopy of clusters, surfaces and interfaces
Experiments with free and supported molecules and clusters
Small Quantum System (SQS) stands for a large number of systems, where their properties are dominated by quantum size effects. This are of research includes systems like atoms, molecules, free ion and clusters, e.g. the number of atoms per system ranges from 1 for the atoms up to several 100 for very big molecules or larger clusters.
Within our group core level spectroscopy on these systems ranging from atoms up to clusters and molecules with a few atoms (around 10) are performed. To access the core levels we are using synchrotron radiation, as as the free electron laser in Hamburg (FLASH). Aim of our experiments is to understand the electronic and magnetic properties of the small quantum systems.
