Dispersion relations were developed for the N-N and N-N elastic scattering amplitudes for neutral, scalar nucleons from causality and unitarity. These were evaluated to fourth order in perturbation theory. The fourth order terms are shown to be about 10% of the pole terms for neutral, scalar nucleons, and low energies, if the coupling constants are not significantiy larger than the pion-nucleon pseudoscalar coupling constant. Dispersion relations were developed for the N-N and N-N elastic scattering amplitudes for charged, spinor nucleons. Mesons with zero strangeness were considered and it is shown that there are ten that interact linearly with the nucleon field, conserving J, P, T, and G. The pole terms of these mesons were determined in the N-N and N-N elastic scattering amplitudes, and the neutron-neutron, proton-proton and neutron-proton differential elastic scattering cross sections were determined from these pole terms. This gives the differential cross sections in terms of twelve coupling constants and ten masses. (Dissertation Abstr.)
