RESONANT PION-NUCLEON INTERACTION AND PRODUCTION OF PIONS BY NUCLEONS

The production of pions by nucleons is studied in an attempt to take approximate account of the strong pionnucleon interaction. The calculation is based on the assumption that the probability of the process N + N yields pi + N + N' is determined by the energy of the created pion relative to one of the nucleons. Using experimental values for the matrix elements of the pion-nucleon interaction, we calculate the spectrum of pions and nucleons im the reaction N + N yields pi r N + N', and also the intensity of pion emission as a functiom of the angle between pion and nucleon. The results are compared with experiment. (auth)
