摘要：

We introduce a new and well defined power counting for the effective field theory describing nucleon-nucleon interactions. Because of the large NN scattering lengths it differs from other applications of chiral perturbation theory and is facilitated by introducing an unusual subtraction scheme and renormalization group analysis. Calculation to subleading order in the expansion can be dune analytically, and we present the results for both the S-1(0) and S-3(1) - D-3(1) channels. (C) 1998 Elsevier Science B.V.
