Photoelectron spectra of negatively charged cobalt clusters in the size range of 4-26 atoms have been obtained. The electron affinity (E.A.) values along with the reported ionization potential (I.P.) have been used to understand the reactivity of neutrally charged cobalt clusters, with H$\sb2$, in terms of their valence electronic structure. Comparison to currently available theories indicate that a charge transfer mechanism (be it from metal to H$\sb2$ or the reverse process) is inadequate in properly explaining the reactivity behavior of these clusters. A third factor, that of Pauli Repulsion, has been found to be significant in controlling the reactivity. An excellent correlation is observed between the promotion energy (E$\sb{\rm p}$) and the observed reactivity of the neutral clusters.
