✦ Synopsis

The electronic structure of small iron clusters is probed with size-selected anion photoelectron spectroscopy. The photoelectron spectra for Fe~ to Fe~6 exhibit consistently sharp features near the threshold and their spectral changes correlate well with changes of their chemical reactivity. Extended Hiickei calculations, based on body centered cubic structures for F% to Fe~6, provide a reasonable explanation of the experiment. These calculations also yield insights into the cluster magnetism and allow an interpretation of the cluster chemical reactivity based on their electronic structure.
