摘要：
A dynamical approach of the meson production reaction for extracting nucleon resonance parameters has been developed. We report on the gamma N Delta form factors extracted from the recent pion electroproduction data and the coupled-channels model of pi N scattering up to W <= 2 GeV. An analysis of the resonance poles extracted using the speed-plot and time-delay methods is briefly discussed.
