摘要：

We have carried out fits to the energy dependence of the P11 partial-wave amplitude as obtained in two different single-energy analyses of -N scattering data. Data on inelastic cross sections were also used. The fits used an analytic approximation to the coupled-channel amplitudes suggested by the Dyson equations. From each set of partial-wave data, two resonances were obtained, at roughly 1470 and 1700 MeV. Each of these resonances is associated with a cluster of poles on the Riemann surface. © 1990 The American Physical Society.
