摘要
We investigate a multichannel ND-1 parametrization for the π-N partial-wave amplitudes. Using a two-channel, one-input-pole form of the model, we present fits to all the interesting π-N partial waves up to pion laboratory kinetic energy ∼1.4 BeV. Reasonable fits are obtained for most of the partial waves. An exceptionally good fit is obtained for the P33 partial wave, in which the N33* resonance appears as a quasi-bound state with respect to the higher-mass inelastic channel. Applications of the model are discussed. © 1969 The American Physical Society.
