Abstract
The observed structure in annihilation implies the existence of a tensor-force effect in charmonium spectroscopy. We show that the magnitude of the effect is consistent with an analysis of levels using a phenomenological Hamiltonian linear in both and , the tensor force. Adding a linear term one can account for all known charmonium levels below 4 GeV and predict the location of the rest of the spectrum, in particular the state at 3.27 GeV.
