We discuss the size dependence of the ionization threshold energy In of small Fe clusters using a simple tight-binding type electronic theory. In agreement with recent experimental results we obtain characteristic structure in In as a function of the number n of cluster atoms. From comparison with experiment we conclude that small Fe-clusters have b. c. c-like structure.
