Abstract
A synergistic approach that combines first-principles theory and electron p hotodetachment experiment is shown to be able to uniquely identify the grou nd state of a nearly degenerate cluster in the gas phase. Additionally, thi s approach can complement the Stern-Gerlach technique in determining the ma gnetic moment of small clusters unambiguously. The method, applied to a Fe- 3 cluster, reveals its ground state to have a magnetic moment of 10 mu(B)-i n contrast with earlier predictions.
