Abstract: (Elsevier)

In this Letter we interpret the Y(4260) , a state recently discovered by the BaBar Collaboration that has a mass within the range of conventional charmonium states, as having a molecular-state structure. In our scheme this molecular-like state is not constructed out of two-quark mesons, but rather out of baryons, i.e., the Y(4260) is a baryonium state. With this interpretation, the unusual measured properties of the Y(4260) are easily understood and some further peculiar decay characteristics are predicted.
