The soft landing experiments on iron clusters reported here were performed at BESSY I and II. Technical assistance from BESSY staff members and from E20 group members at Technische Universität München is gratefully acknowledged. This project was funded by BMBF through grant KS1GUB/5 and by DFG through grant Me 266/22-2.

Soft landing of mass selected clusters in rare gas matrices is a technique used to preserve mass selection in cluster deposition. To prevent fragmentation upon deposition, the substrate is covered with rare gas matrices to dissipate the cluster kinetic energy upon impact. Theoretical and experimental studies demonstrate the power of this technique. Besides STM, optical absorption, excitation, and fluorescence experiments, x-ray absorption at core levels can be used as a tool to study soft landing conditions, as will be shown here. X-ray absorption spectroscopy is also well suited to follow diffusion and agglomeration of clusters on surfaces via energy shifts in core level absorption.
