Nucleon-nucleon partial-wave analysis to 1 GeV

Comprehensive analyses of nucleon-nucleon elastic-scattering data below 1 GeV laboratory kinetic energy are presented. The data base from which an energy-dependent solution and 20 single-energy solutions are obtained consists of 5207 pp data below 1.2 GeV and 5283 np data below 1.1 GeV. The solutions are characterized by tightly constrained "resonancelike" structure in the ¹D₂ and ³F₃ partial waves. No other partial waves exhibit such structure below 1 GeV; in particular, we see no isoscalar resonances. We describe how the full data base and solution files can be accessed through a computer interactive dial-in system [scattering analyses interactive dial-in (SAID)] at VPI, which also exists at several institutions around the world and which can be transferred to any site with a suitable computer system. The SAID system can be used to modify solutions, plan experiments, and obtain any of the multitude of predictions which derive from our partial-wave analyses of the world data base.
