Research in medium-energy theory carried out during 1981 is reviewed. The main interest lies with the nucleon-nucleon system, from abstract theoretical models to data analysis. Several contributions to the VPI and SU NN analysis program are detailed. Because the NN..pi.. final state plays a dominant role in NN scattering at intermediate energies, there is also interest in three-body systems; some theoretical treatments are presented. Pion-deutron scattering and its relevance to the NN interaction is discussed. Nucleons and pions are extended objects, so form factors enter in an essential way. Some estimates based on extended PCAC, or radial excitations of the pion, are presented. Related problems are also being studied, including chiral-symmetry breaking and corrections to the Goldberger-Treiman relation. Development continues on a dynamical theory for isospin and other internal quantum numbers in an extended flat-space.
