In the quark model, nuclei (B 5 2) have exotic quantum numbers. Given a nuclear reaction in which certain quantum numbers a r e exchanged, what i s the scattering amplitude at high energies, in the GeV region? Does it have Regge behavior? I s i t dual? Are there multibaryon resonances? In this context we present a general survey of all high-energy nuclear reactions -mainly those involving light nuclei. For B = 0 exchange reactions, like adad and a-ha 9 (h I 3~e , t = 3~) , there i s the impulse and rescattering (Glauber) model. For

Naively, one might expect an unsubtracted dispersion relation in u, and then assuming that the E-N anomalous cut saturates the dispersion integral. In this approach, the absolute scale of the amplitude is calculable, whereas before it was left as a free parameter. The calculated normalization turns out to be somewhat larger than the experimental value, and to improve on this would require a much deeper understanding of the deuteron structure. Since nuclei apparently lie 4 4 5
