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 {ital pp} (18 {ital np}) single-energy solutions are obtained consists of 11 880 {ital pp} and 7572 {ital np} data. A resonancelike structure is found to occur in the {sup 1}{ital D}{sub 2}, {sup 3}{ital F}{sub 3}, and {sup 3}{ital P}{sub 2}-{sup 3}{ital F}{sub 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 {ital T} matrix obtained in the energy-dependent solution.
