SINGLE PION PRODUCTION PROCESS IN PION-NUCLEON COLLISION AND THE SAKATA MODEL
Based on the Sakata model, a model is proposed for the single pion production process in pi -N collision. It is pointed out that analyses of sub- Bev single pion production phenomena give information about the level scheme of the Sakata model. As a first step of the investigation of this model an analysis of the single pion production process in pi /sup +/-p collision at 500 Mev is made. The model predicts the contribution of the I = 2 boson isobar as well as the I = 3/2 fermion isobar for this process. Such a prediction is consistent with the experimental branching ratio ( pi /sup +/ + p- pi /sup +/ + pi /sup 0/ + p)/( pi /sup +/ + p- pi /sup +/ + pi /sup +/ + n) = 1.5. The energy and angular distribution of the pion and nucleon are useful for obtaining information about the I = 2 boson isobar and I = 3/2 fermion isobar from this process. (auth)
