DISPERSION RELATIONS IN NUCLEON-NUCLEON SCATTERING

;

Two-pion contribution to ihe absorptive part of nucleonnucleon scattering amplitudes in the unphysical region is calculated using the dispersion relation for pion-nucleon scattering. The dispersion relations with this absorptive part are used for analyzing nucleon-nucleon scattering data at low energy and at moderate energy, and good agreement is obtained when the coupling constant is chosen as f/sup 2/4 tion = 0.08 combination rat 0.01.
