During the past several years a great amount of work has been performed on the prediction of NN̄ resonances within the framework of a nonrelativistic potential model.1–4 Such models are based on one boson exchange potentials (OBE) which have been developed for the case of NN̄ scattering. The real part of the NN potential is then obtained by a G-parity transformation which reverses the sign of the coupling in the case of π- and ω-exchange. This procedure leads to the prediction of many strongly bound NN̄ states, since according to the nonrelativistic OBE models, co-exchange is supposed to be responsible for the strong short range repulsion in the NN system and would then give an equally strong attraction in the NN̄ system, at least if the effects of annihilation could be ignored (see below).
