    "abstract": "A resonance model for two-pion production in the pion-nucleon reaction is\ndeveloped that includes information obtained in the analysis of pion-nucleon\nscattering in a meson-exchange model. The baryonic resonances Delta(1232),\nN*(1440), N*(1520), N*(1535), and N*(1650) are included. The model reproduces\nthe total cross sections up to kinetic energies of the incident pion of 350 MeV\nand obtains the shapes of the differential cross sections in reasonable\nagreement with the data.",
