摘要：

An energy-dependent analysis and set of energy-independent analyses are presented for the nucleon-nucleon elastic-scattering data below 1.6 GeV. The database from which the energy-dependent and 25 pp (18 np) single-energy solutions are obtained consists of 11 880 pp and 7572 np data. A resonancelike structure is found to occur in the D-1(2), F-3(3), and P-3(2)-F-3(2) partial waves; this behavior is associated with poles in the complex energy plane. The pole positions and residues are obtained through analytic continuation of the "production" piece of the T matrix obtained in the energy-dependent solution.
