Abstract: Photoelectron spectra of negatively charged Nin- , Cun-, and Con- clusters are presented. The spectra of the Nin- clusters contain information about the degree of localization of the 3d valence orbitals, which is strongly related to the magnetic properties. In the clusters with less than 7 atoms, the 3d orbitals seem to be almost totally localized. For Co13- we find indications of a narrowing of the 3d-derived valence "bandwidth" corresponding to a presumed high symmetry and a high degree of degeneracy of the 3d electronic states.
