Abstract

The treatment of a weak u channel by the usual prescription of exchange degeneracy, based on a potential-theory model, is shown to violate crossing badly. On the other hand, a crossing-symmetric treatment of the same situation would lead to backward superconvergence relations, which provide the basis for a new prescription of exchange degeneracy. Several consequences of this crossing-symmetric prescription of exchange degeneracy are discussed, with particular reference to NN̅ scattering.
